Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 2.560\% 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(N/N=C\c1ccc(Br)cc1)c1ccc(Cn2cccn2)o1
(b) Cc1ccc(S(=O)(=O)NCCCCCC(=O)Nc2ccccc2)cc1
Answer: a. O=C(N/N=C\c1ccc(Br)cc1)c1ccc(Cn2cccn2)o1
