Answer:
B. Complex sentence
Step-by-step explanation:
An independent clause is a clause that can stand alone as a sentence. Every sentence must contain a subject and predicate and express a complete thought.
Dependent clauses are clauses that can't stand alone as they don't contain all elements of a sentence. Their purpose is to provide additional information about what is stated in the independent clause.
A simple sentence is a sentence that consists of one independent clause.
A compound sentence is a sentence that consists of at least two independent clauses.
A complex sentence is a sentence that consists of one independent clause and at least one dependent clause.
The given sentence consists of one independent (... control your sugar intake to stay healthy) and one dependent clause (Because sugary snacks and drinks are unhealthy...), which makes it a complex sentence.
