The correct answer is a) stop codon.

Codons in an mRNA are encoded during translation process of protein synthesis. It begins with a start codon on mRNA and goes till a stop codon is reached. The Codons UAG, UGA and UAA on the mRNA do not encode any amino acids because they are called nonsense or stop codons. A nonsense codon causes end of polypeptide synthesis.

Alla [95]

Explanation:

Epipelagic zone, the topmost at the surface of the oceans receives most of the sunlight and most penetrating light rays diffuse in this layer. The temperatures at this zone, therefore, is warmer than zones below. This zone has lowest water pressure becaue there is little water column above it.

The deeper you get into the water the penetration of sunlight decreases. This is because the rays are greatly diffused even before they get to the deepest zones. The abyssalpelagic zone virtually receives no sunlight because the rays cannot get to this zone. This zone is, therefore, pitch dark and also the coldest. The deeper you get into the ocean the higher the water pressure due to the weight of the able water column. The water pressure is, therefore, highest in the  abyssalpelagic zone.
