Task: Answer the multiple-choice question.
Query: Which drug has a 4.716\% 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. O=c1c2ccccc2nc(-c2ccc([N+](=O)[O-])cc2)n1-c1ccccc1
b. CCOC(=O)C1=CN(C)C=C(C(=O)OCC)C1c1ccsc1
c. CCc1c(C#N)c(N)nc(SCC(=O)OCc2ccccc2)c1C#N
d. O=S(=O)(c1ccc2c(c1)OCCO2)N1CCC(n2nnc3cc(C(F)(F)F)ccc32)CC1
Answer: a. O=c1c2ccccc2nc(-c2ccc([N+](=O)[O-])cc2)n1-c1ccccc1
