gamate - body cells have an EVEN number of choromomes.

They come in pairs - the gamete represents the number of pairs in this case 15.

You need to know the normal number of chromosomes in that organism.  Humans usually have 46 chromosomes.  However, gametes (eggs or sperm) are made by meiosis (reduction division), so they have only half the regular number, and in humans would have 23.

A gamete.
Somatic body cells are normally diploid (2n, in pairs).
15 is not in pairs.

Possibly it could be a diploid body cell with trisomy (1 extra and normal diploid = 14) or with monosomy (1 missing and normal diploid = 16).

given that you said 15 CHROMOSOMES and not 15 chromosome PAIRS, it's a gamete...

This would be a gamete. A gamete has half as many chromosomes as a regular cell, regular cells are usually even numbered, because they occur in pairs. 15 chromosomes would be a gamete because of this.
