Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 13.449\% 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 additional words.
Options:
[a] N/C(=N\OC(=O)Cc1ccc([N+](=O)[O-])cc1)c1cccc(Br)c1
[b] Cc1c(Cl)cccc1NC(=O)NN1CCN(C)CC1
[c] C=CCSc1nnc(CNC(=O)c2ccccc2C)n1C(C)C
[d] O=Cc1ccccc1OCc1ccc2c(c1)OCO2
Answer: d. O=Cc1ccccc1OCc1ccc2c(c1)OCO2
