He didn’t have the . . . . . . . idea of the villager’s problems.

smallest
finest
faintest
feeblest

The correct answer is: C. faintest.

The word “faintest” means “the least amount or degree of something.” In this context, it means that the man did not have even the slightest understanding of the villagers’ problems.

The other options are not as accurate. The word “smallest” means “the least in size or amount.” This does not accurately capture the man’s lack of understanding. The word “finest” means “of the highest quality or standard.” This does not accurately capture the man’s lack of understanding. The word “feeblest” means “the weakest or most ineffective.” This does not accurately capture the man’s lack of understanding.

In conclusion, the correct answer is C. faintest.
