Task: Answer the multiple choice question.
Question: Which drug exhibits a 14.276\% 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=C1C(=O)c2ccc(-c3ccccc3)cc2-c2ccccc21
b.) CC(C)NC(=O)NNc1c(Cl)cncc1Cl
c.) COc1ccccc1C(=O)Nc1ccnn1C1CCN(Cc2cc(C)c(C)cc2C)CC1
d.) CCOc1ccccc1CNc1ccc(N2CCOCC2)c(C(=O)O)c1
e.) COc1ccc(C(C(=O)NCC2CCCO2)N(C(=O)Cn2nnc3ccccc32)c2ccc(NC(C)=O)cc2)c(OC)c1
Answer: a. O=C1C(=O)c2ccc(-c3ccccc3)cc2-c2ccccc21
