Question

What form is the underlined verb in the sentence?

The tour guide led the group through the museum. (Led)

A. present participle

B. past

C. past participle

D. present

Answer 1

The form in the sentence is B. past

Answer 2

I agree with the person above - the underlined word is used in the B. past tense.
A present participle would be - leading, a past participle would be - (has/had) led, and present would be - leads.
