Answer 4

Ans is -14

As (i) It could be represented in the form of p/q, i.e. it is Rational.
(ii) It can be clearly seen that -14 is an Integer having no decimal value.
(iii) All set of numbers that are not imaginary are Real. Imaginary for example square root of -1. :) Other than these, all are real numbers.
