Correct option is C
To determine the code for ‘walking,’ let's examine the sentences and their corresponding codes:
- In the sentence ‘Arjun is walking to school’: ‘walking’ corresponds to ‘AG’.
- In the sentence ‘Krishna is speaking to Arjun’, ‘walking’ is not present.
- In the sentence ‘School is within walking distance of Krishna’, the word ‘walking’ corresponds to ‘AG’ again.
Thus, ‘AG’ is the code for ‘walking’.
