Task: Answer the multiple-choice question.
Query: Which compound exhibits a 4.672\% 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 O=C(CCCN1C(=O)/C(=C/c2ccccc2Cl)SC1=S)NNC(=O)c1ccc(Cl)cc1
b COc1ccc(NC(=O)c2c(Cl)nc3ccccn23)cc1
c Cc1ccc(NC(Cc2cc(C)no2)c2ccccc2)cc1
d Cc1ccccc1/C=C\c1nc2ccccc2c(=O)n1Cc1ccccc1
Answer: a. O=C(CCCN1C(=O)/C(=C/c2ccccc2Cl)SC1=S)NNC(=O)c1ccc(Cl)cc1
