Task: Answer the multiple choice question.
Query: Which drug exhibits a 21.798\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: O=C(O)CCCn1cc(NC(=O)c2ccc(F)cc2)cn1
b: C=CCO/N=C(/C)c1ccc(Oc2cnccn2)cc1
Answer: a. O=C(O)CCCn1cc(NC(=O)c2ccc(F)cc2)cn1
