Task: Answer the multiple-choice question.
Question: Which drug exhibits a 18.428\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) N/C(=N\N=C\c1ccco1)SC1CC(=O)N(c2ccc(C(=O)O)cc2)C1=O
(b) CSc1nnc(N2C(=O)C(O)=C(C(=O)c3ccc(C)o3)C2c2ccc(C)cc2)s1
Answer: a. N/C(=N\N=C\c1ccco1)SC1CC(=O)N(c2ccc(C(=O)O)cc2)C1=O
