Write down your name and roll number. (Choose the right connector:)

This question requires choosing the correct connector to combine two elements in an instruction.

• "Both" is the correct answer. The instruction "Write down your name and roll number" clearly indicates that two pieces of information are required. The connector "Both...and..." is used to emphasize that two items are included or apply, making it the most suitable choice here to ensure both name and roll number are provided.
• "Either" is a distractor because "Either...or..." implies a choice between two options, meaning only one is necessary, which contradicts the instruction.
• "Neither" is a distractor because "Neither...nor..." implies that neither of the two options is applicable or required, which is the opposite of the instruction.
• "Not only" is a distractor; while it includes the first item, "Not only...but also..." is used for emphasis and adding information, not simply listing two required items as effectively as "Both."
