Task: Answer the multiple choice question.
Question: Which drug has a 12.885\% 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, b, or c without using any additional words.
Options:
(a) CC(C)NC[C@H](O)COc1ccc(CC(N)=O)cc1
(b) Cc1ccc(-c2cc(C(F)F)nc(N3CCC(C)CC3)n2)cc1
(c) O=C1C2CC=C(Cl)CC2C(=O)N1CNc1ccccn1
Answer: b. Cc1ccc(-c2cc(C(F)F)nc(N3CCC(C)CC3)n2)cc1
