Select the most appropriate option to fill in the blank.
Raju's various afflictions made his job even _______.

Correct option is B

The correct option to fill in the blank is (b) harder.

Explanation:
The sentence requires a comparative degree because 'even' is used to show a change or comparison to a previous state. The comparative degree of 'hard' is 'harder'.

Example: After the injury, it was even harder for him to walk.

Information Booster:
For one-syllable adjectives like 'hard', we usually add '-er' to form the comparative. We do not use 'more' with words that already have an '-er' form.

So the correct answer is (b)
