Answer 2

Answer:

The answer to the above-mentioned sentence is option B which states that "know". Thus the sentence formed will be "Does she know what she is doing?"

Explanation:

• We are aware that the first verb after "do" or "did" is always in present tense. So, by this rule, we can safely eliminate option C and option D as the verb is in past tense.

• We also know, that by the rule of agreement, the number of verb is equal to the number of subject present in a sentence. So, if there is only one subject, the verb will also be single and vice versa.

Hence, the correct option will be option "b" as it satisfies all the above-mentioned rule.
