Answer

Answer:

B. Increased carbon dioxide levels have made the oceans more acidic.

Explanation:

Step1: Recall CO2 - ocean reaction

When CO2 dissolves in water, it forms carbonic acid (H2CO3).

Step2: Analyze ocean pH change

Carbonic acid dissociates, releasing hydrogen ions (H+), increasing ocean acidity.

Step3: Evaluate options

A is wrong as it makes oceans acidic not alkaline. C is wrong as CO2 doesn't lead to more O2 production. D is wrong as it disrupts not stabilizes ecosystems.
