Task: Answer the multiple-choice question.
Question: Which compound has a 4.865\% 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, c, or d without using any additional words.
Options:
(a) COC(=O)c1ccccc1N=Nc1c(C)noc1C
(b) O=c1c2[nH]cnc2n(-c2ccccc2)c(=O)n1Cc1ccccc1
(c) CO/N=C/NC(=O)c1cn(-c2ccc(F)cc2)c(=O)c2ccccc12
(d) CCn1c(SCC(N)=O)nnc1-c1ccc2c(c1)OCO2
Answer: a. COC(=O)c1ccccc1N=Nc1c(C)noc1C
