Task: Answer the multiple choice question.
Question: Which drug has a 12.519\% 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) CSc1ccc(/C=c2\s/c(=C\C(=O)C(C)(C)C)n(CC(=O)NCCC3=CCCCC3)c2=O)cc1
(b) Cc1ccc(S(=O)(=O)N2CCN(C(=O)c3ccccc3)CC2)c(C)c1NS(C)(=O)=O
(c) O=C(N/N=C\c1ccco1)c1cncc(Br)c1
Answer: c. O=C(N/N=C\c1ccco1)c1cncc(Br)c1
