Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 19.660\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a.) CCC(C)n1c(O)c(C=NC(C)c2ccccc2)c(=O)[nH]c1=S
b.) CCCC(C(=O)O)N1C(=O)/C(=C/c2cccn2C)SC1=S
c.) CCN(CC(=O)Nc1c(F)cccc1F)C(=O)c1cccc(S(=O)(=O)N2CCc3ccccc3C2)c1
d.) CCOC(=O)c1ccc(N2C(=O)CC(Sc3nc(O)c(CC)c(=O)[nH]3)C2=O)cc1
e.) c1ccc2sc(NN=C3CCCC3)nc2c1
Answer: a. CCC(C)n1c(O)c(C=NC(C)c2ccccc2)c(=O)[nH]c1=S
