Answer

To solve the question regarding the oral contraceptives developed by CDRI and their lesser side effects, we can break down the information step by step:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks why the oral contraceptives developed by the Central Drug Research Institute (CDRI) have lesser side effects compared to other contraceptive methods.

2. **Identifying the Product**: The oral contraceptive developed by CDRI is known as "Saheli." It is important to note that this product is distinct from many traditional oral contraceptives.

3. **Composition of Saheli**: Saheli is characterized as a non-steroidal contraceptive. This means it does not contain steroid hormones like estrogen or progesterone, which are commonly found in many other oral contraceptives.

4. **Mechanism of Action**: Saheli works by inhibiting implantation rather than ovulation. This is significant because traditional contraceptives often prevent ovulation, which can lead to hormonal imbalances and various side effects.

5. **Impact on Hormonal Balance**: Since Saheli does not interfere with ovulation and maintains a normal menstrual cycle, it does not cause hormonal disturbances. This lack of hormonal disruption is a key reason why it has fewer side effects compared to steroidal contraceptives.

6. **Conclusion**: Based on the above points, the reason the oral contraceptives developed by CDRI have lesser side effects is that they contain a non-steroidal preparation.

### Final Answer:
The oral contraceptives developed by CDRI have lesser side effects because they contain a non-steroidal preparation (Option A).
