Step 1: Identify the tense and voice of the sentence. The sentence is in the past tense ("did not manage"), so the blank should also be in the past tense.
Step 2: Understand the structure. The phrase "he got it fixed" is the correct causative form in English, meaning "he arranged for someone else to fix it."
Step 3: Eliminate wrong options.
- (B) "getting it fixed" → present participle, grammatically incorrect in this past tense structure.
- (C) "gets fixed" → simple present, does not match past context.
- (D) "got fixed" → incorrect because "he got fixed" changes meaning (implies he was repaired himself).
\[
\boxed{\text{The correct answer is (A) got it fixed.}}
