Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 7.854\% 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.) Cc1ccc(-c2nnc(-c3ccccc3)o2)cc1Br
b.) CC1CN(Cc2c(O)ccc3c2oc(=O)c2ccccc23)CC(C)O1
c.) O=C(COC(=O)c1cccnc1Cl)NCCC1=CCCCC1
d.) COc1ccc(C(=O)NC2CCCc3ccccc32)cc1
Answer: a. Cc1ccc(-c2nnc(-c3ccccc3)o2)cc1Br
