B. Steroid hormone
This is because most hormones are steroids, that send long distance signaling throughout your body.
Because carbohydrates can be converted into energy but can not store energy.

Rna triplets
The nucleotide sequence copy of a gene is present in the mRNA. Each amino acid is represented by a triplet of the four nucleotide bases that make up the genetic alphabet. The relationship between triplet sequences and amino acids is known as the genetic code.
A codon is a triplet of RNA nucleotides that codes for a particular amino acid. To the ribosome, where translation takes place, the tRNA transports certain amino acids. During translation, the anticodons in the tRNA bind to the codons in the mRNA templates. It is essential for the codon and anticodon to interact in order to pair the codon with the appropriate amino acid.
In mRNA, each trio of nucleotides is referred to as a codon, and each codon designates a certain amino acid (hence, it is a triplet code).
