Answer:  Option A - Cesium-133

Explanation:

• Caesium-133 is most commonly used in atomic clocks due to its stable and well-defined frequency of microwave radiation, which is used to keep precise time.
• The caesium atomic clock operates by measuring the vibrations of caesium atoms, providing incredibly accurate timekeeping.
• Uranium-235, Radon-222, and Carbon-14 are used in different applications, such as nuclear reactors and dating techniques, but not in timekeeping.

Answer:  Option A -  Lakshadweep Islands

Explanation:

• The Lakshadweep Islands are renowned for their coral reef ecosystems. Located in the Arabian Sea, these islands feature vibrant coral reefs that support diverse marine life.
• In contrast, Chilika Lake, the Rann of Kutch, and Loktak Lake are known for their unique freshwater and brackish water ecosystems, but they do not have significant coral reef systems.

The Lakshadweep coral reefs are crucial for marine biodiversity and tourism

Answer:  Option D - Elevated sea temperatures causing the expulsion of symbiotic algae from corals.

Explanation:

• Coral bleaching occurs when elevated sea temperatures stress corals, causing them to expel the symbiotic algae (zooxanthellae) living within their tissues.
• This loss of algae, which provide corals with their color and essential nutrients through photosynthesis, results in a bleached appearance and can lead to coral death if conditions do not improve.
• The other options pertain to different stressors or processes affecting coral reefs.
