Task: Answer the multiple-choice question.
Query: Which drug exhibits a 2.430\% human ether-à-go-go related gene (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 additional words.
Options:
a CC(C)Oc1ccc(C(=O)/C(=C\c2cccs2)c2nc3ccccc3o2)cc1
b Cc1c(CCC(=O)NCCCN2CCCC2=O)c(=O)oc2cc(O)ccc12
c COc1ccc([N+](=O)[O-])cc1NC(=O)c1ccc(CN(c2ccccc2)S(C)(=O)=O)cc1
d Cc1cccc(N2CCN(Cc3nc(-c4ccc(F)cc4F)oc3C)CC2)n1
e O=C(CN1C2=NCCCN2c2ccccc21)c1cccs1
Answer: e. O=C(CN1C2=NCCCN2c2ccccc21)c1cccs1
