Task: Answer the multiple choice question.
Question: Which drug exhibits a -6.968% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) Cl.c1csc(CNCc2ccncc2)c1
b) O=C(COC(=O)c1cnccn1)Nc1cccc2ccccc12
c) Cc1ccc(-n2c(N)c(C(=O)N3CCOCC3)sc2=S)cc1
d) O=C(N=Nc1c(O)[nH]c2ccc([N+](=O)[O-])cc12)c1ccccc1[N+](=O)[O-]
Answer: d. O=C(N=Nc1c(O)[nH]c2ccc([N+](=O)[O-])cc12)c1ccccc1[N+](=O)[O-]
