Problem statement: Answer the multiple-choice question.
Question: Which drug has a 16.550\% 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(OCc2nn[nH]n2)c1
b. CCCOc1ccc(NC(=O)CC2C(=O)N(CC)C(=S)N2CCNC(C)=O)cc1
c. COC(=O)/C(N=Nc1c(C)n(C)n(-c2ccccc2)c1=O)=C(\C)O
d. O=C(Nc1nncs1)c1cccnc1Cl
Answer: a. COc1cccc(OCc2nn[nH]n2)c1
