Task: Answer the multiple-choice question.
Question: Which drug has a 1.956\% 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.) CCOC(=O)C1CCN(S(=O)(=O)c2cc(Br)cc3c2N(C(C)=O)C(C)C3)CC1
b.) O=C(Cc1cccs1)NCc1ccco1
c.) Cl.O[C@@H](c1cc(C(F)(F)F)nc2c(C(F)(F)F)cccc12)[C@H]1CCCCN1
Answer: a. CCOC(=O)C1CCN(S(=O)(=O)c2cc(Br)cc3c2N(C(C)=O)C(C)C3)CC1
