Task: Answer the multiple choice question.
Question: Which compound exhibits a 2.845\% 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 CC(=O)NCCOC(=O)Nc1sc(=S)n(C)c1C
b COc1cc(OC)cc(C(=O)NCCC(=O)NCCc2ccc(OC)c(OC)c2)c1
c O=c1c2ccccc2[nH]c(=S)n1Cc1cccnc1
d CCOC(=O)c1cnn(-c2ccccc2)c1NC(=O)c1ccc(C)cc1
Answer: a. CC(=O)NCCOC(=O)Nc1sc(=S)n(C)c1C
