Assertion: INVO cell is a new cost-effective technology for in vitro fertilisation (IVF) in which the sperm and the egg are mixed in a lab,

Two statements are given - one labeled Assertion (A) and the other labeled Reason (R). 

Assertion: INVO cell is a new cost-effective technology for in vitro fertilisation (IVF) in which the sperm and the egg are mixed in a lab, put in a small capsule which is inserted into the vagina for a five days incubation period, post which the capsule is removed, and the embryos are implanted inside the uterus as usual. 

Reason: Instead of growing the embryo in an incubator, allowing it to develop in the natural environment in woman’s vagina reduces the cost in case of INVO cell as compared to regular IVF technology. 

Which of the following is correct?

 A. Both A and R are true, and R is the correct explanation of the assertion. 

B. Both A and R are true, but R is not the correct explanation of the assertion. 

C. A is true, but R is false.
