The sentence is divided into four segments: (A), (B), (C), and (D). Identify the segment that contains a grammatical error. If the sentence is both grammatically and contextually correct, select “No error” as the correct answer.

After completing (A)/ the application, (B)/ you must submitting it (C)/ and pay the fees at the counter. (D)

Correct option is C

Sentence given:
After completing (A)/ the application, (B)/ you must submitting it (C)/ and pay the fees at the counter. (D)
Step 1: Spot the error
Look at (C): “you must submitting it.”
· Rule: After a modal verb (must, can, should, will, may, etc.), the main verb always takes its base form (without -ing, -ed, or “to”).
· So instead of “must submitting,” it should be “must submit.”
Step 2: Grammar rule
Modal Verb + Base Verb Rule
· Structure: Subject + modal verb + base verb + object
· Example: You must complete the form. (not must completing or must completed)
Step 3: Sentence structure
· Subordinate clause: After completing the application
· Main clause: you must submit it and pay the fees at the counter.
Step 4: Corrected sentence
After completing the application, you must submit it and pay the fees at the counter.
Step 5: Example for clarity
Incorrect: She can singing very well.
Correct: She can sing very well.
Correct Answer: (c) C
