c. Metheonine

Explanation:

All the tRNAs are charged with amino acids to serve in protein synthesis. It refers to the process of attachment of correct amino acids to the respective tRNA. Each tRNA has an amino acid arm to carry the specific amino acid. The amino acid is bonded in ester linkage to the 3' end of the tRNA.

The initiation codon in eukaryotes is "AUG" which in turn codes for amino acid "methionine". Therefore, the initiator tRNA that first binds to the mRNA-small ribosomal sub-unit complex to start the process of protein synthesis carries methionine at its amino acid arm. The initiator tRNA of prokaryotes carries formyl-methionine as the initiator amino acid.

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )
