Assertion (A) : The super ovulation in cow is induced by hormonal injection of FSH and after artificial insemination 4-6 embyos are collected .
Reason : Each embryo is transplanted into carrier cow (surrogate mother ) , or is deep frozen in liquid nitrogen at `-196^(@) C` for several years , or is cut into two to obtain identical twins .

Options

A. Both A and R are correct and R is the correct explanation of A
B. Both A and R are correct but R is not the correct explanation of A
C. A is true but R is false
D. A is false and R is true

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states that superovulation in cows is induced by hormonal injection of FSH (Follicle Stimulating Hormone) and that after artificial insemination, 4-6 embryos are collected.
- Superovulation refers to the process where a cow is stimulated to produce multiple eggs in one cycle instead of the usual one.

2. **Understanding the Reason (R)**:
- The reason explains that each embryo is either transplanted into a surrogate mother (carrier cow), deep-frozen in liquid nitrogen at -196°C for several years, or bisected to obtain identical twins.
- This describes the methods of handling the embryos after they are collected.

3. **Evaluating the Assertion**:
- The process of inducing superovulation using FSH is well-documented and accurate. The collection of 4-6 embryos post artificial insemination is also a common practice in embryo transfer techniques.

4. **Evaluating the Reason**:
- The reason provided is also accurate. Embryos can be transplanted into surrogate mothers, preserved through cryopreservation, or bisected to create identical twins.
- However, the reason does not directly relate to the assertion; it provides additional information about what can be done with the embryos after they are collected.

5. **Conclusion**:
- Both the assertion and the reason are correct statements, but the reason does not explain or support the assertion directly. Therefore, the correct answer is that both A and R are correct, but R is not related to A.

### Final Answer:
Both A and R are correct, but R does not relate to A.
