b.

Burning fossil fuels raises atmospheric CO2, which dissolves in seawater to form carbonic acid and lowers pH (ocean acidification). (The other choices are incorrect: burning fossil fuels warms oceans indirectly via greenhouse warming, pollution/nutrient runoff tends to increase algal blooms, and added warm water does affect marine life.)
