Answer 1

The Correct Option is B

Step 1: Fehling’s solution reaction. Fehling’s solution is a mixture of copper sulfate and alkali used to test for aldehydes. Formic acid (a form of aldehyde) reduces Fehling’s solution, while other acids do not.
Step 2: Conclusion. Thus, formic acid reduces Fehling’s solution.
