Answer

Brief Explanations:

A compound sentence is made up of two independent clauses. When joining two independent clauses with a coordinating conjunction (like "but"), a comma should be placed before the conjunction. Let's analyze each option:

Option 1: A semicolon is used incorrectly here. Semicolons are for joining independent clauses without a conjunction.
Option 2: The colon is misused. Colons are for introducing explanations or lists.
Option 3: The comma is in the wrong place. It should be before "but", not after "formula".
Option 4: This correctly places a comma before the coordinating conjunction "but" to join the two independent clauses.

Answer:

Dr. Burke wanted to trust her assistant with the secret formula, but she was afraid her assistant was a spy.
