I was trying to solve this question of this year asked in GATE2019 Exam.They asked that among the following which can be the pumping length of Language.
1.)9  2.)24  3.)5   4.)3

I tired to solve like this. I divide the minimum string possible into x(y^i)z that is a^2 so getting i value 2 but option not available. Then I take second minimum a^5 i.e taking x=E and y=a^5 and z=E. I am getting i=5. So is it correct answer??
