Task: Answer the multiple-choice question.
Query: Which drug has a 0.128\% 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(c1ccncc1)N1CCN(S(=O)(=O)c2cc(C(F)(F)F)cc(C(F)(F)F)c2)CC1
b. CCC(=O)Nc1ccc(NC(=O)CSc2nnnn2-c2cccnc2)cc1C
c. CC(=O)Nc1ccccc1C(=O)C(=O)Nc1cccc(C(=O)NC2CC2)c1
d. O=C(NNC(=O)c1cc(F)c(F)cc1Cl)c1ccc(NS(=O)(=O)c2cccs2)cc1
Answer: a. O=C(c1ccncc1)N1CCN(S(=O)(=O)c2cc(C(F)(F)F)cc(C(F)(F)F)c2)CC1
