Task: Answer the multiple choice question.
Question: Which drug has a 19.532% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a CCc1c(C)nc2nc(SCc3ccccc3Cl)[nH]n2c1=O
b NS(=O)(=O)c1ccc(-c2ccc(/C=C3\C(=O)Nc4ccccc43)o2)cc1
c N#Cc1cccc(CN2CCC(=O)N(CCO)CC2)c1
d COc1ccc(CCN2C(=O)CSC2=Nc2ccc(C)cc2C)cc1OC
Answer: a. CCc1c(C)nc2nc(SCc3ccccc3Cl)[nH]n2c1=O
