Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -0.643\% 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 other words.
Options:
a. O=C(Nc1ccc2oc(-c3ccccc3F)nc2c1)c1cncc(Br)c1
b. CN(C)c1cccc(C(=O)OCC(=O)Nc2nccs2)c1
c. Clc1ccc(CN=C(Nc2ccccc2)NC2CCCCC2)cc1
d. CSCCC(NC(=O)c1ccc(Cl)c([N+](=O)[O-])c1)C(=O)N1CCN(C/C=C/c2ccccc2)CC1
e. O=C(Cc1ccccc1)NNS(=O)(=O)c1ccc(F)cc1
Answer: c. Clc1ccc(CN=C(Nc2ccccc2)NC2CCCCC2)cc1
