a. They are not numbers, but are useful in solving equations.
b. they are the values of expression of the form sqrt-a for various real numbers a, as long as a does not equal 0.
c. They are the complex numbers
================
They are complex numbers with the real part = zero.
eg, 2i = 0 + 2i
-------
They are complex numbers, but I wouldn't say "the complex numbers."
=================
d. they consist of two values, the principal imaaginary number i and its negative -1.
