Problem statement: Answer the multiple-choice question.
Query: Which drug has a 13.689\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a. N=C1C(c2ccccc2)=C(O)CN1CCO
b. COc1ccc(C)cc1N(C(=O)c1ccco1)C(C(=O)NC1CCCC1)c1ccc(N2CCOCC2)cc1
c. N#CC1(NC(=O)CN2C(=O)NC3(CCCCCC3)C2=O)CCCCC1
Answer: a. N=C1C(c2ccccc2)=C(O)CN1CCO
