Task: Answer the multiple-choice question.
Query: Which compound exhibits a 13.378\% 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 O=S(=O)(c1ccccc1)C(/C=N\O)/C=C/c1ccccc1
b COc1ccc(OC)c(-c2cc(C(=O)N3CCOCC3)no2)c1
c Cc1ccc2[nH]c(-c3ccccc3)c(CN(C)C)c(=O)c2c1
d CN(C)c1ccc(/C=N/NC(=O)c2ccc(Cn3cc(Br)cn3)o2)cc1
Answer: a. O=S(=O)(c1ccccc1)C(/C=N\O)/C=C/c1ccccc1
