Task: Answer the multiple choice question.
Question: Which drug exhibits a 2.170\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a O=C(CC(=O)Nc1ccccn1)Nc1ccccn1
b O=C(Nc1cccn2ncnc12)c1ccc(Cl)cc1Cl
c CCN(CC)CCCNc1oc(-c2ccc(OC)c(OC)c2)nc1C#N
d Cc1nnsc1NC(=O)OCc1ccc(Cl)cc1Cl
Answer: d. Cc1nnsc1NC(=O)OCc1ccc(Cl)cc1Cl
