Task: Answer the multiple-choice question.
Question: Which drug exhibits a 11.276\% 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: O=C(O)/C=C/c1ccc(OCCCF)cc1
b: COc1cccc(-n2c(=S)[nH]c3c(oc4ccccc43)c2=O)c1
c: CCCSCCCNC(=O)CC1Oc2ccccc2NC1=O
d: CC1CC(C)(C)NC(=S)N1CCC(=O)N1CCc2ccccc21
Answer: b. COc1cccc(-n2c(=S)[nH]c3c(oc4ccccc43)c2=O)c1
