Task: Answer the multiple choice question.
Question: Which compound has a 4.900\% human ether-à-go-go related gene (hERG) inhibition at 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=C(NC1CCCC1)c1cccc(Oc2ccccc2)c1
[b] CCOc1ccccc1NC=C1C(=O)OC2(CCCCC2)OC1=O
[c] CCc1noc(C)c1C(=O)OC(C)C(=O)NCc1ccc(OC)cc1
[d] CCN1C(=O)c2ccccc2S(=O)c2ccc(C(=O)NCc3ccccn3)cc21
[e] COc1cc2c(cc1OC)/C(=C/C(=O)c1ccccc1F)NCC2
Answer: a. O=C(NC1CCCC1)c1cccc(Oc2ccccc2)c1
