Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 2.647\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) O=C(N/N=C/c1cc(Br)ccc1O)C(=O)Nc1ccccc1OC(F)(F)C(F)F
(b) CCOC(=O)CN(C(=O)Cn1nnc(-c2ccc(C)cc2)n1)C(CC)C(=O)NC1CCCC1
Answer: a. O=C(N/N=C/c1cc(Br)ccc1O)C(=O)Nc1ccccc1OC(F)(F)C(F)F
