Solution

The correct option is A Mercury
The increase in enzyme activities correlates with highest mercury accumulation in the kidneys and liver. Mercury generates reactive oxygen species (ROS). Therefore, the enzyme activities increased to scavenge ROS levels produced as a result of mercury accumulation. The kidneys accumulate the highest levels of mercury compared to brain and liver.
So, the correct answer is option B.
