Which one of the following is a group of words that includes a subject and a verb and expresses a complete thought? subordinate clause uncompleted clause sentence fragments independent clause flag question

Bonjour

An independent clause includes a subject, a verb and expresses  a complete thought (une proposition indépendante).

As its name implies, it stands alone.

A main clause  (proposition principale) could stand alone but it's followed by a relative pronoun or a subordinating conjunction attaching it to a subordinate clause (proposition subordonnée)

A subordinate clause is attached to the main clause.

exemples=>

he likes the cake ---> main clause

he likes the cake that you cooked -- > main clause + subordinate clause

hope this will help :)
