Explanation

To solve the question, we need to identify the drug (A) and the organism (B) mentioned in the statement. Here’s the step-by-step solution:

### Step 1: Understand the Question
The question states that a drug used for patient A is obtained from organism B. We need to identify both A and B.

### Step 2: Analyze the Options
We will look at the options provided to find a match between a drug and the organism it is derived from.
