D. None is correct

Answer

To determine the alkene A that undergoes ozonolysis to yield the given products, we can follow these steps:

### Step 1: Understand the Ozonolysis Reaction
Ozonolysis is a reaction where an alkene reacts with ozone (O₃) to form ozonides, which can subsequently decompose to yield carbonyl compounds (aldehydes or ketones). The general idea is that the double bond in the alkene is cleaved, and oxygen is added to form carbonyl groups.

### Step 2: Analyze the Products
The products given are:
1. CH₃CHO (acetaldehyde)
2. CH₃C(=O)C(=O)CHO (which is essentially two carbonyl groups, indicating a compound with two aldehyde functionalities)

### Step 3: Identify the Structure of Alkene A
To find the alkene A that would yield these products upon ozonolysis, we can reverse the ozonolysis reaction:
- The presence of CH₃CHO suggests that one of the fragments must be an aldehyde with a methyl group.
- The other fragment must also contain a carbonyl group.

### Step 4: Construct the Alkene
To produce both CH₃CHO and CH₃C(=O)C(=O)CHO, we can consider the following:
- The alkene must have a structure that, when cleaved, results in these two products.
- A plausible alkene structure is 2-butene (CH₃-CH=CH-CH₃), which upon ozonolysis would yield:
- CH₃CHO from one end of the double bond.
- CH₃C(=O)CHO from the other end.

### Step 5: Confirm the Reaction
When 2-butene undergoes ozonolysis, it would yield:
- From one side: CH₃CHO (acetaldehyde)
- From the other side: CH₃C(=O)CHO (which can be represented as CH₃C(=O)C(=O)CHO)

Thus, the alkene A that would yield the products specified in the question is **2-butene**.

### Final Answer
Alkene A is **2-butene**.
