Yes, A.

You are correct! Sentence A is a compound-complex sentence.

A compound-complex sentence is made up of two or more independent clauses (compound) and one or more dependent clauses (complex).

In sentence A, we have two independent clauses: "After the massacre occurred, the government started an investigation" and "no one expected to find anything." These two independent clauses are joined by a coordinating conjunction "but," creating a compound sentence.

Additionally, we have a dependent clause "After the massacre occurred" at the beginning of the sentence, which makes it complex. So, with two independent clauses and one dependent clause, sentence A is a compound-complex sentence.
