Step 1: Understanding the Concept:
This question tests the use of causative verbs. A causative verb is used when one person causes another person to do something. The common structures are "have something done" or "get something done".
Step 2: Key Formula or Approach:
The grammatical structure for the causative verb "get" is:
Subject + get (in the correct tense) + object + past participle.
Step 3: Detailed Explanation:
1. The first part of the sentence, "He did not manage to fix the car himself," is in the past tense. This indicates that the second part of the sentence should also be in the past tense.
2. The subject is "he".
3. The past tense of the verb "get" is "got".
4. The object is the car, which is represented by the pronoun "it".
5. The action performed on the car is "fix", and its past participle is "fixed".
6. Applying the structure: he (subject) + got (get in past tense) + it (object) + fixed (past participle).
This perfectly matches option (A).
Step 4: Final Answer:
The correct phrase to complete the sentence is "got it fixed".
Step 5: Why This is Correct:
Option (A) correctly uses the past tense causative structure. Option (B) uses the present participle "getting," which doesn't fit the past tense context. Option (C) uses the present tense "gets," which is incorrect. Option (D) "got fixed" is grammatically awkward and incomplete; it's missing the object "it".
