Explicação:

O Present Continuous (alternativa F) é usado para indicar ações que estão em progresso no presente.

A estrutura na forma afirmativa é:

Sujeito + verbo to be (am/is/are) +  verbo principal com a terminação –ing

Ex: I am cooking.

Conjugação do verbo to be:

I - am

you - are

he/she/it - is

we - are

you - are

they - are
