Option a is correct .

Answer 2

Answer:

The correct answer is (a) 1st trimester and the details of this question we will see in the explanation part.

Explanation:

If we talk about the first trimester then from conception to the 12th week of pregnancy  is marked as the first trimester. There is the possibility that the fetal heartbeat may be first detected by the vaginal ultrasound around 6 week after gestation. It is the first visible sign of a developing embryo and sometimes we can see it also. At the end of 1st trimester that means after 12th week heartbeat begins in the embryonic development. After this trimester the remaining two trimester i.e. 2nd trimester and 3rd trimester takes place.
