In his lust for wealth, he had reached the zenith of criminal activity.

acme
nadir
bottom
end

The correct answer is A. acme.

The word “acme” means

the highest point or level of something. In this case, the man had reached the highest point of criminal activity in his lust for wealth.

The word “nadir” means the lowest point or level of something. This is not the correct answer because the man had reached the highest point of criminal activity, not the lowest.

The word “bottom” can mean the lowest point or level of something, but it can also mean the foundation or base of something. This is not the correct answer because the man had reached the highest point of criminal activity, not the lowest.

The word “end” can mean the final point or limit of something, but it can also mean the purpose or goal of something. This is not the correct answer because the man had reached the highest point of criminal activity, not the final point or limit.
