Choose the correct option:
A
Your grammar is very good, but you need to work on correcting your pronunciation.
B
Your grammar is very good, but you need to work on repairing your pronunciation.
C
Your grammar is very good, but you need to work on managing your pronunciation.
D
Your grammar is very good, but you need to work on modifying your pronunciation.
Correct option is A. Your grammar is very good, but you need to work on correcting your pronunciation.
Option A: 'Correcting' means 'rectifying an error', or 'improve upon an error'. It is relevant to the given sentence in meaning, the person in question 'you' must improve upon the errors in their pronunciation.
Hence option A is correct.
Option B: 'Managing' means 'being in charge of'.
Option C: 'Repairing' means 'fixing something that is damaged'.
Option D: 'Modifying' means 'making changes to'.
Theses words are not relevant in meaning. They do not form complete meaningful sentences. Hence options B, C and D are wrong.
