An organic compound 'A' `(C_(9)H_(10)O)` when treated with conc. HI undergoes cleavage to yield compounds ‘B’ and ‘C’. ‘B’ gives yellow precipitate with `AgNO_(3)` where as ‘C’ tautomerizes to ‘D’. ‘D’ givespositive iodoform test. ‘A’ could be :

Options

A.
B.
C.
D.

Explanation

To solve the problem, we need to identify the organic compound 'A' with the molecular formula \( C_9H_{10}O \) based on the reactions it undergoes when treated with concentrated HI.

### Step-by-Step Solution:

1. **Understanding the Reaction with HI**:
- The compound 'A' reacts with concentrated HI, leading to cleavage. This suggests that 'A' likely contains a functional group that can be cleaved by HI, such as an alcohol or ether.

2. **Identifying Compounds 'B' and 'C'**:
