A compound that gives a positive iodofrm test is `:`

Options

A. 1-pentanol
B. 3-pentanone
C. 2-pentanone
D. pentanal

Explanation

To determine which compound gives a positive iodofrom test, we need to identify compounds that contain either a methyl ketone group (CH3CO-) or a secondary alcohol with a methyl group adjacent to the hydroxyl group (CH3CHOH-).

### Step-by-Step Solution:

1. **Understand the Iodofrom Test**:
The iodofrom test is a qualitative test for the presence of methyl ketones or secondary alcohols with a methyl group. The reaction occurs in the presence of a base (like NaOH) and iodine (I2), leading to the formation of iodoform (CHI3).

2. **Identify the Functional Groups**:
