Problem statement: Answer the multiple choice question.
Query: Which drug has a 15.938\% 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.) O=C(CSc1ncn[nH]1)NNC(=O)c1ccccc1
b.) Cc1cc(C(=O)NNC(=O)CCC2CCCCC2)c(C)o1
c.) O=C(CCCCn1c(=O)[nH]c2ccccc2c1=O)NC1CCN(Cc2ccccc2)CC1
d.) O=CNNC(=O)c1cccc([N+](=O)[O-])c1
Answer: d. O=CNNC(=O)c1cccc([N+](=O)[O-])c1
