Answer: option b

Step-by-step explanation:

First, we have to find out the approximate value of \sqrt5 which is

2.236067.........
option a) is clearly rational as its decimals are ending at a point.
option c) is rational as even though its decimals are not ending but 50 is repeating in a sequence so it can be expressed as a rational number.
option d) is rational for the same reason mentioned for option c). 5000 is repeating in a sequence.

option b) is irrational as neither are the decimals ending nor are they repeating in a sequence

.: option b) is your answer.
