Task: Answer the multiple choice question.
Question: Which drug exhibits a 13.831\% 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, d, or e without using any other words.
Options:
a O=C(c1ccsc1)N1CCCC(Nc2cccc(F)c2)C1
b CC12CCCCC1N(O)C(=O)C(=O)N2O
c COc1cc2c(cc1NC(=O)CN(C)Cc1nc3ccccc3c(=O)[nH]1)oc1ccccc12
d CCn1c(C)c(CS(=O)(=O)c2ccccc2)[nH]c1=O
e O=C(c1cccc2ccccc12)C1CCCN(Cc2ccon2)C1
Answer: b. CC12CCCCC1N(O)C(=O)C(=O)N2O
