Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 8.042\% 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, or d without using any other words.
Options:
a COC(=O)C1=C(N)OC2=C(C(=O)CC(C)(C)C2)C1c1cccs1
b CC(=O)Nc1ccc(S(=O)(=O)N2CCN(C(=O)N3CCOCC3)CC2)cc1
c Cc1cccc(Cn2c(N(C)Cc3ccccc3)nc3c2c(=O)[nH]c(=O)n3C)c1
d CCCCCCN1C=CC=C/C1=C/C=C(C#N)C#N
Answer: c. Cc1cccc(Cn2c(N(C)Cc3ccccc3)nc3c2c(=O)[nH]c(=O)n3C)c1
