Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A: Endometrium is necessary for implantation of blastocyst.
Reason R: In the absence of fertilization, the corpus luteum degenerates that causes disintegration of endometrium.
In the light of the above statements, choose the correct answer from the options given below:
Both A and R are true and R is the correct explanation of A .
Both A and R are true and R is NOT the correct explanation of A .
A is true but R is false.
A is true but R is true.
Answers (1)
Option 2) Both A and R are true, but R is NOT the correct explanation of A.
The assertion (A) that the endometrium is necessary for implantation of the blastocyst is true. The endometrium provides the necessary environment for the embryo to attach and establish a connection with the maternal blood supply.
The reason (R) provided, stating that the degeneration of the corpus luteum causes the disintegration of the endometrium, is not the correct explanation for the necessity of the endometrium. The degeneration of the corpus luteum and the subsequent decrease in hormone levels contribute to the shedding of the endometrium during menstruation but do not directly explain the requirement of the endometrium for blastocyst implantation.
Therefore, option 2 is the correct answer. Both statements are true, but the reason does not explain the assertion.
