Task: Answer the multiple-choice question.
Question: Which drug exhibits a 1.968\% 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=C(c1cccc([N+](=O)[O-])c1)N1CCCN(C(=O)c2cccc([N+](=O)[O-])c2)CC1
b CCn1nc(C)c(NC(=O)CC23CC4CC(CC(C4)C2)C3)c1C
c CCCCOc1ccc(C(O)(CCN2CCOCC2)c2ccccc2)cc1.Cl
d Cc1ccc(C2=NS(=O)(=O)N(C)C(C(=O)NC3CCCC3)=C2)cc1
Answer: d. Cc1ccc(C2=NS(=O)(=O)N(C)C(C(=O)NC3CCCC3)=C2)cc1
