Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 3.902\% 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(N/N=C/c1cccc(Cl)c1Cl)Nc1ccccc1
b: CC(C)(C)NC(=O)NC(=O)COC(=O)c1c(F)cccc1Cl
c: CS(=O)(=O)Nc1ccc(C(=O)Nc2ccccc2C(=O)N2CCCC2)cc1
d: CN1CCN(c2c(F)cc3c(=O)c(C(=O)O)cn4c3c2SCC4)CC1.Cl
e: O=C(c1ccc(S(=O)(=O)N2CCOCC2)cc1)N1CCN(c2ccc(F)cc2)CC1
Answer: a. O=C(N/N=C/c1cccc(Cl)c1Cl)Nc1ccccc1
