As we have already discussed in Implantation -

  • Implantation is the attachment of the blastocyst to the wall of the uterus of the mother. 
  • It occurs about a week after fertilization. 
  • The portion of the blastocyst where the inner cell mass is located lies against endometrium. 
  • At the point of contact, the trophoblastic cells digest and engulf the endometrial cells and thus, blastocyst sinks into a pit formed in the endometrium.
  • Then the blastocyst is completely buried in the endometrium. 
  • The blastocyst forms villi by means of which it establishes an intimate contact with the uterine wall. 
  • The blastocyst derives nutrition and lives as a parasite within the uterus of the mother.
     Hence the correct option is (a).
