Explanation:

Let's go through the options:

- Option 1: C-iii-E

- "Our dog barks although someone walks by our house."

- This is incorrect as it suggests opposition which doesn't logically fit.

- Option 2: B-iii-D

- "The Sharmas liked their new home, although sometimes they missed their friends."

- This is a correct and logical contrast between liking the new home and missing friends.

- Option 3: B-i-E

- "The Sharmas liked their new home whenever someone walks by our house."

- This doesn't make sense contextually.

- Option 4: C-i-F

- "Our dog barks whenever everyone else was in the meeting."

- Temporal mismatch makes this option incorrect.

- Option 5: A-i-E

- "I decided to take a nap under my desk whenever someone walks by our house."

- The relationship doesn't logically connect.
