The right answer is D.
A gamete is a generally haploid reproductive cell specialized in fertilization, or gamy (that is to say, able to fuse with another gamete, complementary type if necessary), in eukaryotes.
The process that carries out the fusion of two gametes is called fertilization or gamy, it is the complementary event of meiosis. Fertilization produces a new single cell, called a zygote, whose chromosome number has doubled to 2n.

The correct answer is D) production of a zygote with a complete set of chromosomes with genetic material from two parents
The nucleus of a cell is haploid if it has a single set of chromosomes, diploid if it has two sets of chromosomes etc.
Gametes are haploid cells in sexually reproducing organism. During fertilization (conception) in organisms that sexually reproduce, two gametes (haploid cells) fuse with one another which results in a production of a zygote with a complete set of chromosomes with genetic material from two parents. In this case, the zygote is going to be diploid.
