We know the Mathematical rules that

$$\begin{gathered} ++ = + \\ +- = - \\ -+ = - \\ -- = + \end{gathered}$$

Two digit numbers: The two digits can be 2 and 9: Two possibilities 29 and 92.

Three-digit numbers: The three digits can be 1, 2 and 9 => 3! Or 6 possibilities.

We cannot have three digits as (3, 3, 2) as the digits have to be distinct.

We cannot have numbers with 4 digits or more without repeating the digits.

So, there are totally 8 numbers.

Any number which can be expressed as a fraction of two integers like P & Q as P/Q where Q is not equal to zero.

Hence, 4 is a rational number in the given options.
