We arranged many meetings and collected many signatures.

We have arranged many meetings and many signatures are collected.
Many meetings are arranged, many signature are collected by us.
Many meetings were arranged and many signatures were collected by us.
Many meetings has arranged and many signatures has collected by us.

The correct answer is: C. Many meetings were arranged and many signatures were collected by us.

The other options are incorrect because they use the wrong tense or voice.

  • Option A uses the present perfect tense, but the action of arranging meetings and collecting signatures is in the past.
  • Option B uses the passive voice, but the action is not passive.
  • Option D uses the simple present tense, but the action is in the past.

The correct sentence should be:

  • Many meetings were arranged and many signatures were collected by us.

This sentence uses the past tense to describe the action of arranging meetings and collecting signatures. It also uses the active voice to indicate that the action was done by us.
