Task: Answer the multiple-choice question.
Question: Which drug has a 21.466\% 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 CC(C)(CC(=O)O)CC(=O)N1CCCN(c2nc3ccc(Cl)cc3s2)CC1
b COc1ccc2cc(C(=O)/C=C/c3cc(OC)c(O)c(OC)c3)ccc2c1
c CCOc1ccc(Br)cc1CNCc1cccnc1
d Cc1nn(C2CCCO2)c(=O)nc1N
e O=C(Nc1ccc(O)c(-c2nc3ccccc3s2)c1)c1cc(=O)c2ccccc2o1
Answer: d. Cc1nn(C2CCCO2)c(=O)nc1N
