A.1 B.2 C.3 D.4 E.5

IMO. Answer should be E.

4 of them who study Cooking and yoga includes 2 who participate in all three.
So who ONLY study cooking and yoga is 2.(absolutely correct)

From that who study ONLY cooking and weaving are 10- ( ONLY study cooking and yoga)- (participate in all three.) - (study cooking only)

= 10 -2-2-3 = 3
(everything is fine with your calculationn but they have asked both cooking and weaving and not only cooking and weaving)

But what here asked is people who study both cooking and weaving = (ONLY cooking and weaving) + (participate in all three) = 3 + 2 = 5

Correct me if I am wrong.
