Task: Answer the multiple-choice question.
Question: Which drug exhibits a -0.861\% 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 Cc1ccc(S(=O)(=O)N(CC(=O)NCc2ccccn2)c2ccc(Cl)cc2)cc1
b COc1ccc(C2CC3(CC(C)(C)NC(SC)=N3)Oc3cc(O)cc(C)c32)cc1.I
c CC1(C)CC(=O)C2=C(C1)OC(N)=C(C#N)[C@@]21C(=O)N(CC(N)=O)c2ccccc21
d NC1=NC(=O)/C(=C/c2cc(Br)c(O)c(Br)c2)S1
Answer: a. Cc1ccc(S(=O)(=O)N(CC(=O)NCc2ccccn2)c2ccc(Cl)cc2)cc1
