Answer:
Compound-complex.
Step-by-step explanation:
A compound-complex sentence is elucidated as the sentence comprising of a minimum of two or more correlated independent clauses along with a minimum of one or more subordinate or dependent clauses. These sentences primarily intend to present the complex or longer thoughts through the various parts of the sentence coherently.
As per the question, the given sentence exemplifies a 'compound-complex' sentence as it consists of one subordinate clause('Because they provide toys for children') followed by two independent clauses ('fast-food restaurants like McDonald's have become immensely popular among families' and ' the price of a Happy Meal makes them a great choice for parents as well as kids') which are appropriately punctuated and linked with the conjunctions 'because'(subordinate) and 'and'(coordinate). Thus, it justifies the above claim and hence, it demonstrates a 'compound-complex' sentence.
