____________________

Step-by-step explanation:

{x | x < 0}

-A all positive integers (false because x is negative)

-B all positive real numbers numbers (false because x is negative)

-C None of these (true)

-D all negative real numbers (false because 0 must be in the set)

-E all negative integers (false because 0 must be in the set)

In other words, 0∈E and 0 ∉ {x | x < 0}.
