Problem statement: Answer the multiple choice question.
Query: Which drug has a 16.913\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a O=C1CCC([N+](=O)[O-])C(c2ccc(F)c(Br)c2)N1
b O=C(Nc1ccc(N2CCCCC2)cc1)c1cc(S(=O)(=O)N2CCOCC2)ccc1F
c COc1ccc2c(C(F)(F)F)cc(=O)oc2c1C
d Cc1cccc(N2CCN(C(=O)c3ccc(NS(=O)(=O)c4ccc5[nH]c(=O)[nH]c5c4)cc3)CC2)c1C
Answer: a. O=C1CCC([N+](=O)[O-])C(c2ccc(F)c(Br)c2)N1
