Which one of the following is a singular word?
c: mathematics.

Eg.: 1 wife - 2 wives / 1 knife - 2 knives / 1 half - 2 halves

The noun "mathematics", as other sciences, ends with the suffix "ics", and as so it is considered to be a singular noun, since it is the name of a single science.
Eg.: physics - robotics - linguistics - ethics, etc.
