Consider the following statements

Marine clouds primarily form from sulfates and sea salt crystals.
In clean maritime air, marine clouds have larger droplets with higher light reflection.
The process of Marine Cloud Brightening (MCB) can reduce the frequency and severity of coral bleaching events.

How many of the above statements is/are correct?

Only One

Only Two

All Three

None

Only statements 1&3 are correct.

Mechanism of Marine Cloud Brightening

In clean maritime air, clouds primarily form from sulfates and sea salt crystals, which are relatively scarce, leading to larger droplets with lower light reflection.
Marine cloud brightening (MCB) seeks to boost marine cloud reflectivity (albedo), making clouds whiter and brighter.
It involves using water cannons or specialized vessels to release fine sea water droplets into the atmosphere.
As these droplets evaporate, they leave behind salt particles, serving as cloud condensation nuclei that foster the formation of denser, brighter clouds.

Potential Benefits

MCB has the potential to lower sea surface temperatures in targeted areas, potentially reducing the frequency and severity of coral bleaching events.
This could provide a lifeline for corals, enabling their survival and recovery while the world transitions away from fossil fuels.

Hence option 2nd is correct.
