Task: Answer the multiple choice question.
Query: Which drug exhibits a 17.808\% 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.) COc1ccc(CNc2oc(-c3cccc4ccccc34)nc2P(=O)(OC)OC)cc1
b.) C=C(C)Cn1c(C)cc(C)c(S(=O)(=O)c2ccc(C)cc2)c1=O
c.) Cc1ccc(N2CC(C(=O)NCc3cccnc3)CC2=O)cc1
d.) COc1ccccc1NS(=O)(=O)c1cccc(C(=O)N/N=C(\C)c2ccc3c(c2)OCCO3)c1
e.) O=C(NCc1cccc(Cl)c1)c1ccc2nc[nH]c2c1
Answer: e. O=C(NCc1cccc(Cl)c1)c1ccc2nc[nH]c2c1
