Question

Fill in the blank with the most appropriate word.
The doctor advised her _____ in bed for a week.

• A. stay
• B. to staying
• C. staying
• D. to stay

Answer 1

The correct option is D to stay

The infinitive verb is a verb with the word 'to' in front of it. This verb is always just a verb. There is no - ed, no - ing, no - s at the end of the verb. Thus, options A, B and C are wrong according to the rule. The correct option is D since 'to' is in front of the verb 'stay'.
