Task: Answer the multiple-choice question.
Question: Which compound exhibits a 10.045\% 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, c, or d without using any additional words.
Options:
(a) COCCNc1oc(-c2ccc(F)cc2)nc1C#N
(b) Cc1cc(C(=O)O)c(S(C)(=O)=O)s1
(c) O=C(COc1ccc(=O)n(-c2ccccc2)n1)Nc1ccccc1
(d) COc1ccc(/C=N/OCC(=O)N=Nc2c(O)[nH]c3ccc(Br)cc23)cc1
Answer: b. Cc1cc(C(=O)O)c(S(C)(=O)=O)s1
