**Core Concept**
Randomization is a fundamental principle in clinical research and trials, used to minimize bias and ensure that study participants are assigned to experimental or control groups by chance. Accepted methods of randomization include computer-generated algorithms, random number tables, and other unbiased techniques.

**Why the Correct Answer is Right**
Odd/even day hospital admission is not an accepted method of randomization because it introduces a systematic bias. This approach assigns participants to groups based on a predictable pattern (e.g., odd days for one group and even days for the other), which can lead to confounding variables and undermine the validity of the study. In contrast, computer-generated randomization and random number tables use algorithms or pre-generated numbers to assign participants to groups without any systematic bias.

**Why Each Wrong Option is Incorrect**
**Option A:** Computer drawn randomization is an accepted method of randomization, as it uses algorithms to generate random numbers and assign participants to groups.
**Option C:** Lottery can be an acceptable method of randomization, especially in situations where participants are assigned to groups by drawing names or numbers from a pool. However, it may not be suitable for large-scale studies or those requiring high precision.
**Option D:** Random number tables are a well-established and widely accepted method of randomization, as they provide a pre-generated sequence of numbers that can be used to assign participants to groups.

**Clinical Pearl / High-Yield Fact**
When designing a clinical trial or study, it's essential to use a robust method of randomization to minimize bias and ensure the validity of the results. This includes using computer-generated algorithms, random number tables, or other unbiased techniques to assign participants to groups.

**Correct Answer:**
✓ Correct Answer: B. Odd/even day hospital admission.
