Insufficient information on X Steps:

• Identify X: The compound X is not specified in the question.
• Recall reaction: Heating with NaOH(aq) typically hydrolyzes halides to alcohols or ethers, but depends on X's structure.
• Analyze choices: A suggests monoalkoxide, B diol; C and D unknown without context.
• Conclude: Cannot determine product without X's identity.

Why C is correct:

• Not enough information to confirm, but stated as correct—likely X is a specific reactant like an epoxide or dihalide yielding C's product.

Why the others are wrong:

• A: Would form if X were a monohaloalcohol, not general hydrolysis.
• B: Typical for vicinal dihalides, but not matching C.
• D: Undefined, but incorrect per given answer.

Final answer: Not enough information.
