Answer 1

C ) Have know sidney since my childhood.

O presente perfeito é marcado pela forma:  Sujeito + have/has + verbo principal no particípio + complemento.  Susan has been to England (Susan esteve na Inglaterra). O present perfect pode ser usado para frases que ocorreram e ocorrrem até hoje, ex: She has worked at the hospital since April. (Ela trabalha/ tem trabalhado no hospital desde abril).  I have exercised at the gym lately. (Eu tenho me exercitado na academia ultimamente).  They have organized their wedding. (Eles têm organizado o casamento deles).
