Answer:
B. Verb: be mood: imperative.
Step-by-step explanation:
The sentence provided here exemplifies the imperative mood of the verb i.e. "be mood" as the another verb "dripping" acts an adjective here. So, the action verb is "be" as it illustrates a suggestion which is the main action of the statement and since, it is a suggestion, it exemplifies the imperative mood of the verb. The first option is incorrect as it suggests indicative mood which does not justify the statement provided here. The last two are inappropriate as they treat "dripping" as the verb which is actually acting here as a modifier of noun or adjective. Thus, the second option is correct.
