Question

Fill in the blank with the most appropriate option.

She ____ worried about something.

• A. looks
• B. looking
• C. look
• D. none of these

Answer 1

The correct option is A looks

The sentence refers to an action which is a general truth in the present context. Thus, the verb will take a simple present tense.
"Looks" in option A is correct as it is the third person present form of the verb 'look'. This can be used to represent a general truth.
"Looking" in option B is the gerund form of the verb by '+ ing'. This converts it into a noun and is incorrect.
"Look" in option C is incorrect as it is in subject verb disagreement. Look is used with plural subjects.
As option A "looks" is correct, option D "none of these" is void.
