Task: Answer the multiple choice question.
Query: Which drug has a 0.751\% 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 C[C@H](NC(=O)c1ccc(Cl)c(S(=O)(=O)N2CCOCC2)c1)c1nc2ccccc2[nH]1
b O=c1[nH]c2ccc(S(=O)(=O)N3CCN(c4ccccc4F)CC3)cc2s1
c COc1ccc(S(=O)(=O)NCC2CCCN(C(=O)CN3CCCCC3)C2)cc1
d O=C1CC(SCCc2nc3ccccc3[nH]2)C(=O)N1c1ccc(F)cc1
Answer: d. O=C1CC(SCCc2nc3ccccc3[nH]2)C(=O)N1c1ccc(F)cc1
