Task: Answer the multiple-choice question.
Question: Which drug exhibits a 15.889\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. COCc1cc(OC)nc(-c2csc(C)n2)n1
b. COc1cc(C(=O)Oc2cc(N)n(S(=O)(=O)c3ccccc3)n2)cc(OC)c1OC
c. NCCNc1ccc(C(=O)N2c3ccccc3Sc3ccccc32)cc1[N+](=O)[O-]
Answer: a. COCc1cc(OC)nc(-c2csc(C)n2)n1
