Task: Answer the MCQ question.
Question: Which drug has a 2.421\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) CCCn1nnnc1NC(=O)CSc1ccc(Cl)cc1
(b) O=C(N=Nc1c(O)[nH]c2ccccc12)c1cccc(S(=O)(=O)Nc2ccccc2Cl)c1
(c) C/C(CC(=O)Nc1ccccn1)=N\NC(=O)c1ccc(C)cc1
(d) CCN(CC)N=Nc1[nH]nc2nc(C)cc(C)c12
Answer: c. C/C(CC(=O)Nc1ccccn1)=N\NC(=O)c1ccc(C)cc1
