Task: Answer the multiple choice question.
Question: Which drug exhibits a 1.554\% 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.) COc1ccc(NC(=O)CS(=O)CC(=O)Nc2cccnc2)cc1
b.) O=C(NC(c1ccccc1)c1ccccc1)C1CCCC1
c.) CC(C)OCCCn1c(-c2ccc(Br)cc2)c[nH]c1=S
d.) O=Cc1ccc2noc(-c3ccc(Cl)cc3)c2c1
Answer: d. O=Cc1ccc2noc(-c3ccc(Cl)cc3)c2c1
