Task: Answer the multiple-choice question.
Question: Which drug has a 16.766\% 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: COc1cccc(-c2nnc(NC(=O)c3ccccc3Br)o2)c1
b: Cc1nnc(SCC(=O)Nc2ccc3c(c2)OCO3)n(N)c1=O
c: CCOCCc1c(O)nc(SC)[nH]c1=O
d: Cc1ccccc1Nc1nc(Cl)c(C=O)s1
Answer: c. CCOCCc1c(O)nc(SC)[nH]c1=O
