Answer 1

The correct option is C a- r, b- p, c- q, d- t

Chlorophyll is the green colored pigment which is present in the plastid. It is located in the thylakoid membranes of the plastids. It has a molecular formula of C${}_{55}$H${}_{72}$O${}_{55}$N${}_{44}$Mg. Magnesium is centrally located in the chlorophyll.

Cysteine is a amino acid which has sulphur in it. The molecular formula is HO${}_2$CCH(NH${}_2$)CH${}_2$SH.

Thyroxine and triiodothyronine are the hormones which are secreted by thyroid gland. The thyroid hormones are formed by the attachment of the iodine to the tyrosine residue.

Manganese is required for enzyme activity.

So, the correct answer is option C.
