Task: Answer the multiple choice question.
Query: Which compound exhibits a 17.997\% 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. CCC(=O)NCCc1nc2cc(NC(=O)COc3ccccc3)ccc2n1C
b. O=c1c2ccccc2nc(-c2ccc(Br)cc2)n1Cc1ccccc1
c. CCOC(=O)c1ccc(NC(=S)NN2CCN(C)CC2)cc1
d. Cl.NC1=NCc2ccccc21
e. O=C(Nc1ccc(F)c([N+](=O)[O-])c1)C1CCCO1
Answer: a. CCC(=O)NCCc1nc2cc(NC(=O)COc3ccccc3)ccc2n1C
