Task: Answer the multiple-choice question.
Query: Which drug exhibits a 2.969\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. O=C1NC(=O)N(Cc2ccccc2Cl)C(=O)/C1=C/N1CCOCC1
b. COC(=O)c1cc(N=Nc2sc(N)nc2C)cc(C(=O)OC)c1
Answer: a. O=C1NC(=O)N(Cc2ccccc2Cl)C(=O)/C1=C/N1CCOCC1
