Problem statement: Answer the multiple choice question.
Query: Which drug has a -18.740\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) CCOC(=O)c1nnn(CC(=O)N2N=C(c3ccc(Cl)cc3)CC2c2ccccc2)c1C(=O)OCC
(b) CCOC(=O)c1cc(-c2ccccc2)sc1NC(=O)C(C)Sc1nnc(N)s1
Answer: a. CCOC(=O)c1nnn(CC(=O)N2N=C(c3ccc(Cl)cc3)CC2c2ccccc2)c1C(=O)OCC
