Task: Answer the multiple choice question.
Query: Which drug exhibits a 9.111\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: Cc1ccc(-c2nc(SC(C)C(=O)c3c(N)n(C)c(=O)n(C)c3=O)n[nH]2)cc1
b: CCCCCN1CC(O)=C(c2ccccc2)C1=N
c: COCCn1c(=NC(=O)/C=C/c2cccs2)sc2cc(NC(C)=O)ccc21
Answer: b. CCCCCN1CC(O)=C(c2ccccc2)C1=N
