The following sentence has been split into four segments. Identify the segment that contains a grammatical error.
Nothing hinders the cat / from reaching its master / whenever it listening / to his voice.

Correct option is B

Option (b) contains a grammatical error.
The error is in the phrase "whenever it listening."
The correct form should be "whenever it listens" because "listening" is incorrect in this context.

The correct sentence should be: "Nothing hinders the cat from reaching its master whenever it listens to his voice."
Grammatical rule used:
· Subject-verb agreement in habitual actions: When describing habitual actions with "whenever," the verb should be in the simple present tense.
