A.
B.
C.
D.

Explanation

To solve the problem, we need to identify the structure of compound (x) with the molecular formula C7H12, which undergoes ozonolysis to yield compounds P and Q. We know that:

1. Compound P responds to Tollen's test and iodoform test.
2. Compound Q does not respond to either test.

### Step-by-Step Solution:

**Step 1: Analyze the molecular formula C7H12**
- The molecular formula C7H12 indicates that the compound is likely an alkene or a cycloalkane due to the degree of unsaturation.

**Step 2: Understand the ozonolysis process**
- Ozonolysis is a reaction where alkenes are cleaved by ozone (O3) to form carbonyl compounds (aldehydes or ketones). In this case, we are performing reductive ozonolysis using Me2S (dimethyl sulfide), which will reduce the ozonide intermediates to aldehydes and/or ketones.

**Step 3: Identify compound P**
- Since compound P responds to Tollen's test, it must be an aldehyde (as ketones do not give Tollen's test).
- Additionally, P must also respond to the iodoform test, which indicates the presence of a methyl group adjacent to a carbonyl group (i.e., CH3C(=O)-).

**Step 4: Determine the structure of P**
- The simplest structure for P that fits these criteria is CH3C(=O)H (acetaldehyde) or a similar aldehyde with a methyl group. However, since it must be a product of ozonolysis, we can deduce that it could be 3-methylbutanal (CH3CH2C(=O)CH3).

**Step 5: Identify compound Q**
- Since compound Q does not respond to Tollen's or iodoform tests, it must be a compound that does not contain an aldehyde or a methyl ketone. A possible structure for Q could be a cyclic compound or a simple alkane that does not have the required functional groups.

**Step 6: Determine the structure of compound (x)**
- To find the structure of compound (x), we can consider the possible structures that would yield P and Q upon ozonolysis. The structure of (x) must be an alkene that, when ozonolyzed, produces one aldehyde (P) and one compound (Q) that does not react with Tollen's or iodoform tests.

**Final Structure:**
- After analyzing the possible structures, the correct structure for compound (x) is likely to be 3-methyl-1-hexene, which upon ozonolysis gives 3-methylbutanal (P) and cyclohexane (Q).
