Task: Answer the multiple choice question.
Question: Which compound exhibits a 7.639\% 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=C(c1ccc(Oc2ccccc2)cc1)c1nc2c(n1O)CCCC2
b: Br.Cc1ccc(Nc2nc(-c3ccc(S(=O)(=O)N4CCOCC4)cc3)cs2)cc1Cl
c: N#Cc1cc2c(nc1SCc1ccc(Cl)cc1)CCCC2
d: O=c1cc(-c2ccc(Cl)cc2)[nH]c2ccccc12
Answer: d. O=c1cc(-c2ccc(Cl)cc2)[nH]c2ccccc12
