Task: Answer the multiple choice question.
Question: Which drug exhibits a 7.203\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CCCCn1c(N)c(N(CC(C)C)C(=O)CSCc2cccc(C)c2)c(=O)[nH]c1=O
b: O=C1CCCN1CCCNC(=S)Nc1ccc(F)cc1
c: CC(=O)c1cccc(NC(=O)c2ccc(Br)o2)c1
d: CCn1c(=O)n(CC)c2cc(N3CCCC3)c(NC(=O)c3cccc(OC)c3)cc21
Answer: b. O=C1CCCN1CCCNC(=S)Nc1ccc(F)cc1
