Task: Answer the MCQ question.
Question: Which drug exhibits a 10.539\% 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 additional words.
Options:
[a] Cn1c(O)c(/C=N/N2CCOCC2)c(=O)n(-c2ccccc2)c1=S
[b] C=CCN(C(=O)CSC1=NC(=O)CN1C(C)=O)c1nc(C)c(-c2ccccc2)s1
[c] COc1ccccc1C(=O)Nc1ccc(OC(C)C(=O)N2CCOCC2)cc1
[d] CC1(C)CC(=O)C=C(Nc2ccc(Br)cn2)C1
Answer: d. CC1(C)CC(=O)C=C(Nc2ccc(Br)cn2)C1
