Task: Answer the multiple choice question.
Query: Which drug exhibits a -68.485% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a. C=CCNCC(=O)NN=C(c1ccccc1)c1ccccc1
b. CCCN(CCC)S(=O)(=O)c1ccc(NC(=O)Cc2cccs2)cc1
c. CCNc1nc2[nH]c(=O)c3c(c2s1)OC(N)=C(C#N)C3c1ccc(C)cc1
Answer: a. C=CCNCC(=O)NN=C(c1ccccc1)c1ccccc1
