Task: Answer the multiple choice question.
Question: Which compound exhibits a 3.156\% 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.) c1ccc(-n2nnnc2Cc2nnnn2-c2ccccc2)cc1
b.) CCOC(=O)c1[nH]c2ccc(OC)cc2c1NC(C)=O
c.) CCOc1ccc(N(C(=O)Cn2nnc3ccccc32)C(C(=O)NC(C)(C)CC)c2cccn2C)cc1
d.) N=c1c2ccccc2nnn1-c1cccc(C(F)(F)F)c1
e.) O=C1CCCN1c1ccc(S(=O)(=O)Oc2cccc(Cl)c2)cc1[N+](=O)[O-]
Answer: b. CCOC(=O)c1[nH]c2ccc(OC)cc2c1NC(C)=O
