Task: Answer the multiple choice question.
Query: Which compound has a 21.518\% 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, or c without using any additional words.
Options:
a O=C(Nc1ccccc1Cl)NC1(C(=O)N2CCCCC2)CCCCC1
b O=c1[nH]c(NCc2ccccc2)nc2c1CCC2
c Cc1cc(C(=O)N2CCCc3ccccc32)ccc1[N+](=O)[O-]
Answer: a. O=C(Nc1ccccc1Cl)NC1(C(=O)N2CCCCC2)CCCCC1
