Which scenario follows the rapid dissolution of Antarctic carbonates?

A)Increased krill populations reduce ocean pH
B)Enhanced stratification limits CO2 absorption
C)Glacial retreat exposes vulnerable bedrock
D)Sea ice formation raises surface salinity

💡 Explanation

Glacial retreat uncovers limestone bedrock, where dissolution occurs because of direct exposure to acidic meltwater, therefore chemical weathering accelerates, rather than ocean acidification, stratification, or rising salinity causing such rapid and localized bedrock impacts.
