Can you please explain ... I am getting confuse bcz in one of questions it's says 4 Boolean variables,how many expression can be formed ???

And option is a-16

b-256

c-1024

d- 64*1024

Getting confused

With 4 variable you can represent 16 (i.e 24) different number, each one can be map to either 0 or 1, Therefore everyone has 2 choices, so total 216 boolean function is possible, i.e 26 * 210  (i.e 64 * 1024) is correct answer.
