Problem statement: Answer the multiple choice question.
Question: Which drug has a 19.285\% 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) O=c1[nH]cnc2nn(-c3ccccc3)nc12
b) CCc1cccc2c(C(=O)COC(=O)c3cnc(C)cn3)c[nH]c12
c) CN1CCN(C(=O)C2CCCN(S(=O)(=O)c3ccc(Br)cc3)C2)CC1
d) CCC(C)[C@H](NC(=O)NC1CCCc2ccccc21)C(=O)O
e) Cc1ccc(NC(=O)c2ccc3ccccc3n2)cc1S(=O)(=O)N1CCOCC1
Answer: a. O=c1[nH]cnc2nn(-c3ccccc3)nc12
