Task: Answer the multiple-choice question.
Question: Which drug exhibits a 14.787\% 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 additional words.
Options:
a. CC(=O)/C(C#N)=C1\NC(=O)C(Cc2ccc(C)c(C)c2)S1
b. Cn1c2ccccc2c2cc(C(=O)N3CCOCC3)sc21
c. O=c1c2c3c(sc2ncn1/N=C/c1ccccc1)CCCC3
d. Cc1cc(NC(=O)c2cc(-c3ccccn3)nc3ccccc23)no1
e. COc1ccc2[nH]c(C(=O)O)c(NS(=O)(=O)c3ccc(OC)c(OC)c3)c2c1
Answer: b. Cn1c2ccccc2c2cc(C(=O)N3CCOCC3)sc21
