Task: Answer the multiple-choice question.
Question: Which compound has a -31.984\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a.) O=C(Cn1c(N2CCN(C/C=C/c3ccccc3)CC2)nc2ccccc21)c1ccccc1
b.) C=CCO/N=C(/C)c1c(O)c(CC)c(-c2ccccc2)n(-c2ccccc2)c1=O
c.) O=C(OCC(=O)N1CCCC1)c1ccc(OC(F)(F)F)cc1
Answer: a. O=C(Cn1c(N2CCN(C/C=C/c3ccccc3)CC2)nc2ccccc21)c1ccccc1
