Answer:  Option C - Entanglement principle

Explanation:

• Uncertainty principle deals with the inherent limitations of knowing both the position and momentum of a quantum particle with perfect accuracy. It doesn't directly address secure communication.
• Superposition principle allows a quantum particle to exist in multiple states simultaneously. While it plays a role in quantum communication, it's not the sole security principle.
• Entanglement principle describes a phenomenon where two quantum particles become linked, sharing the same fate regardless of distance. This allows for secure communication through Quantum Key Distribution (QKD), where any eavesdropping attempt disrupts the entanglement and alerts the communicating parties.
• Relativity principle deals with the relationship between space, time, and gravity. It has no direct connection to secure communication in quantum technology.

Answer:  Option B - Maharashtra

Explanation:

• Vadhavan port is situated near Dahanu in Palghar district, Maharashtra.
• It is being developed to serve as an all-weather, deepwater mega port, aiming to enhance maritime infrastructure and facilitate increased trade activities in the region.
• This development is significant for Maharashtra's coastal economic strategy and India's broader maritime trade objectives.

Answer:  Option B - DNA sequences that can move within the genome

Explanation:

• Transposons, or "jumping genes," are DNA sequences that can move from one location to another within the genome.
• This ability to change position can influence gene expression and genome stability, playing a significant role in genetic diversity and evolution.

Unlike static genes, transposons can insert themselves into new genomic sites, sometimes disrupting normal gene function or creating new regulatory patterns

Answer:  Option C -  Low Surface Area

Explanation:

• Graphene, characterized by its excellent electrical conductivity, high strength-to-weight ratio, and honeycomb lattice structure, contradicts the notion of low surface area.
• Its two-dimensional structure confers a remarkably high surface area relative to its volume, enhancing its potential for various applications in electronics, materials science, and energy storage.
• Thus, graphene's properties include high surface area rather than low surface area.

Answer:  Option D - Anthrax, Rabies, Ebola

Explanation:

• Anthrax, Rabies, and Ebola are all zoonotic diseases, meaning they can be transmitted from animals to humans.
• Anthrax often infects humans through contact with infected animals or their products, Rabies is typically transmitted through animal bites, and Ebola can be transmitted through contact with infected animals, such as bats or primates, and through human-to-human transmission.
