Task: Answer the multiple-choice question.
Question: Which drug has a 1.571\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) O=C(c1cccc([N+](=O)[O-])c1)N1CCCC(C(=O)N2CCCCCC2)C1
(b) O=C(Cn1cc(C(F)(F)F)ccc1=O)N/N=C/c1ccccc1O
(c) O=C1[C@@H]2Cc3c([nH]c4ccccc34)C(c3ccccc3)N2C(=O)CN1C1CCN(Cc2ccccc2)CC1
Answer: b. O=C(Cn1cc(C(F)(F)F)ccc1=O)N/N=C/c1ccccc1O
