Task: Answer the multiple choice question.
Question: Which compound exhibits a 17.919\% 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 additional words.
Options:
a O=c1[nH]cnc(O)c1C(c1ccc(F)cc1)c1c(O)nc[nH]c1=O
b CCN(CC)C(=O)c1ccc(N(Cc2ccccc2)S(C)(=O)=O)cc1
c COc1ccccc1/C=C/CN1CCCC(CCC(=O)NCc2ccccc2F)C1
d CCOC(=O)C1CCN(Cc2ccc(Cl)c(Cl)c2)CC1
Answer: a. O=c1[nH]cnc(O)c1C(c1ccc(F)cc1)c1c(O)nc[nH]c1=O
