Task: Answer the multiple-choice question.
Question: Which drug has a 17.851\% 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 other words.
Options:
a: COc1ccccc1N(CC(N)=O)S(=O)(=O)c1ccc(C)cc1
b: O=C(NCCSCc1ccco1)c1ccc(=O)[nH]c1
c: O=C(N/N=C/c1c(O)n(CCc2ccc(F)cc2)c(=O)[nH]c1=O)c1ccccc1
d: CN(C)C(=O)C1C2NC(=S)N(c3ccccc3)C1(C)Oc1ccccc12
Answer: b. O=C(NCCSCc1ccco1)c1ccc(=O)[nH]c1
