Task: Answer the multiple-choice question.
Query: Which drug has a 20.778\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a Cc1c(C(=O)C(=O)NCCc2ccc(S(N)(=O)=O)cc2)c2ccccc2n1C
b CCC(CC)COC(=O)C1=C(C)NC(=O)NC1c1cccc([N+](=O)[O-])c1
c CCOP(=O)(c1ccccc1)C(O)c1ccccc1
d O=C(Nc1nc(-c2cc(Cl)sc2Cl)cs1)c1cccs1
Answer: d. O=C(Nc1nc(-c2cc(Cl)sc2Cl)cs1)c1cccs1
