C. it contains centchroman
D. it decreases risk of cancer

Answer

### Step-by-Step Solution:

1. **Understanding Saheli**: Saheli is an oral contraceptive pill designed for female contraception. It is known for its high effectiveness and low side effects.

2. **Components of Saheli**: The key ingredient in Saheli is centchroman, which is a non-steroidal compound. This is significant because most traditional oral contraceptives contain steroidal hormones, which are often associated with various side effects.

3. **Mechanism of Action**: The non-steroidal nature of centchroman allows Saheli to provide effective contraception without the common side effects linked to steroidal contraceptives. This is a crucial factor in its high contraceptive value.

4. **Dosage Schedule**: Saheli is taken once a week, which is a convenient regimen compared to daily pills. This ease of use contributes to its effectiveness in preventing unintended pregnancies.

5. **Evaluating the Options**:
- **Option A**: "It is taken once in a week" - This is true, but it does not explain why it has high contraceptive value.
- **Option B**: "It contains synthetic progesterone" - This is incorrect; Saheli does not contain synthetic progesterone.
- **Option C**: "It contains centchromone" - This is correct and is the primary reason for its high contraceptive value and low side effects.
- **Option D**: "It decreases risk of cancer" - This is not directly related to its contraceptive value.

6. **Conclusion**: The correct answer is that Saheli has a high contraceptive value with little side effects because it contains centchromone, a non-steroidal component.

### Final Answer:
Saheli is an oral contraceptive pill that has very high contraceptive value with little side effects because it contains centchromone.
