Explanation:
A sentence is said to be a simple sentence if it has one subject and one predicate and it usually has a complete thought.
No. 2 is a simple sentence and a conjunction. It is a conjunction because of the word "that" which is used to introduce the woman.
A sentence is said to be a compound sentence when it has at least two independent clauses which are connected by semicolon, conjunction or comma.
No. 1 is a compound sentence and a conditional sentence. It is conditional because of the use of the word, "if".
No. 3 is a compound sentence and a disjunction. It is disjunction because of the word "or" that was used. Disjunction uses the word "or" to separate clauses.
