Task: Answer the MCQ question.
Question: Which drug exhibits a 16.881\% 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, or c without using any other words.
Options:
a COC(CN1CCc2c(C)nc3c(C#N)cnn3c21)OC
b O=C(COc1ccc(/C=N/NC(=O)c2ccc(O)cc2)cc1)Nc1ccc([N+](=O)[O-])cc1
c O=C(CCn1c(=S)oc2ccccc21)Nc1ccccc1Br
Answer: c. O=C(CCn1c(=S)oc2ccccc21)Nc1ccccc1Br
