How many complete SETS of chromosomes does a cell with a haploid number of four (n=4) have? Explain briefly.?

I legit am SO CONFUSED by this whole ploidy deal in cells. Everything made sense until I hit this. Can someone please help me through this question.

PS. A clarification of the difference between SETS regarding to diploid and haploid cells would be appreciated!

Thanks so much in advance!!!

A haploid cell have only one complete set of chromosomes. The haploid number (n) is the number of chromosomes within the nucleus of a cell that constitutes one complete chromosomal set. So it doesn't matter what the value of n is, a haploid cell have only one complete set of chromosomes .The haploid number is different for different organisms.

A set of chromosomes contains a single copy of every gene required by the organism. This is called the haploid number and is identified by n, as in your example. So a haploid number is one complete set of chromosomes.

Some organisms such yeast are haploid and have only one copy of each gene.

Most organisms including humans are diploid and have 2 copies of each chromosome which they get from each parent and 2 copies of every gene. They have 2 complete sets and are labelled 2n, they have 2 copies of chromosome 1, chromosome 2 etc.

Some organisms may have higher ploidies - mainly plants. A tetraploid plant has 4 sets of chromosomes, 4 copies of chromosome 1, chromosome 2 etc.
