Verified step by step guidance

Identify the reaction type: The reagent [Ag(NH3)2]+ is commonly used in the Tollens' test, which is a specific test for aldehydes. It oxidizes aldehydes to carboxylic acids.

Examine the product structure: The product is a carboxylic acid with a cyclopentane ring and a carboxyl group attached to a two-carbon chain.

Determine the starting material: Since the reagent is used to oxidize aldehydes, the starting material should be an aldehyde that corresponds to the carboxylic acid product.

Analyze the options: Look for a structure that has an aldehyde group (a carbonyl group with a hydrogen attached) that can be oxidized to the carboxylic acid in the product.

Select the correct starting material: The structure with a cyclopentane ring and an aldehyde group attached to a two-carbon chain is the correct starting material for this reaction.
