Task: Answer the multiple-choice question.
Question: Which compound exhibits a 7.666\% 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.) C=CCn1c(Oc2ccccc2)nc2c1c(=O)n(C)c(=O)n2C
b.) S=C(c1cn(CCOc2cccc3ccccc23)c2ccccc12)N1CCCC1
c.) O=C(COc1ccc(S(=O)(=O)N2CCOCC2)cc1)NCCc1ccccc1
d.) O=C(CCC(=O)c1ccccc1)NC1CCCN(Cc2ccccc2F)C1
Answer: a. C=CCn1c(Oc2ccccc2)nc2c1c(=O)n(C)c(=O)n2C
