Is this supposed to be irrational numbers? --> b. international numbers

Although, I really like the idea of international number.

directrix · Answer

Let's eliminate options. To help you get started, a rational number is the ratio of two integer where the denomination is not 0. 

4 = 4/1 so yes, 4 is rational.

directrix · Answer

d. imaginary numbers  

An imaginary number is, for example, the square root of a negative number. 
4 does not fit that definition.

Okay, @B.R   which of the remaining two options do you think are correct?
