Problem statement: Answer the multiple choice question.
Question: Which drug has a 3.873\% 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. O=C(NC1CCCCC1)C1CC(=O)N(CCc2ccc(F)cc2)C1
b. Cc1ccc(/C(N)=N/OC(=O)CCCc2ccccc2)cc1
c. Cc1ccc(-c2nnn(CC(=O)N(Cc3cccs3)C(C(=O)NC(C)(C)C)c3ccco3)n2)o1
d. Nc1c(Cl)cc(C2=NCCn3nc4cc([N+](=O)[O-])ccc4c32)cc1Cl
e. O=C(NCC(O)COc1ccc([N+](=O)[O-])cc1)c1ccccc1
Answer: a. O=C(NC1CCCCC1)C1CC(=O)N(CCc2ccc(F)cc2)C1
