Task: Answer the multiple choice question.
Question: Which compound has a 2.513\% 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 CC1CCN(S(=O)(=O)c2ccc3[nH]c(=O)c(=O)[nH]c3c2)CC1
b COC(OC)C1(C)C(C#N)=C(N)Oc2c1c(=O)oc1ccccc21
c CC(/C=N/NC(=O)CSc1nc(C)cc(C)n1)=C\c1ccccc1
d OC1(C2(O)CC(c3ccccc3)ON2)CCCCC1
Answer: a. CC1CCN(S(=O)(=O)c2ccc3[nH]c(=O)c(=O)[nH]c3c2)CC1
