Which of the acids given below is the strongest acid?

Options

A. `CH_(2)`FCOOH
B. `CH_(2)` ClCOOH
C. `"CHCl"_(2)` COOH
D. `CHF_(2)` COOH

Explanation

To determine which of the given acids is the strongest, we need to analyze the stability of the conjugate bases formed when each acid donates a proton (H⁺). The stability of the conjugate base is crucial because the more stable the conjugate base, the stronger the acid.

### Step-by-Step Solution:

1. **Identify the Acids**: Let's denote the given acids as follows:
- Acid 1: R-COOH (with a specific substituent)
- Acid 2: R-COOH (with a different substituent)
- Acid 3: R-COOH (with another substituent)
