Task: Answer the multiple-choice question.
Query: Which compound exhibits a -6.535\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a O=C(CN1C(=O)C2CC=CCC2C1=O)OCc1cc(=O)n2cc(Br)ccc2n1
b CCN1CCCC1CN=Cc1c(O)n(-c2ccccc2)c(=O)c2ccccc12
c CCCNC(=O)COC(=O)/C=C/c1ccc2c(c1)OCO2
d COC(=O)c1nn(-c2cccc(C(F)(F)F)c2)ccc1=O
Answer: a. O=C(CN1C(=O)C2CC=CCC2C1=O)OCc1cc(=O)n2cc(Br)ccc2n1
