Question

we had no car at that time.

Answer 1

had sold
have finished
have had
has started ??? (не видно вариант С)

Различия между had and have (past participate and present participate) не всегда  отличимы и более видны из контескта. Не знаю как учитель отреагирует, но порой можно сказать и так и так (думаю учетиля английского будут спорить )) )
