Task: Answer the multiple choice question.
Question: Which compound exhibits a 3.219\% 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 additional words.
Options:
a.) S=c1[nH]nc(-c2ccco2)n1/N=C/C=C/c1ccccc1
b.) COc1ccccc1C(=O)NNC(=O)c1ccc(NC(=O)c2ccccc2)cc1
c.) O=C(NC(=S)Nc1ccc(Br)cc1)C1CCC1
d.) COC(=O)c1c(NC(=O)c2nn(C)cc2Cl)sc2c1CCCC2
Answer: a. S=c1[nH]nc(-c2ccco2)n1/N=C/C=C/c1ccccc1
