Task: Answer the multiple-choice question.
Query: Which drug exhibits a 4.240\% human ether-à-go-go related gene (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(N/N=C\c1ccc(Br)o1)C1COc2ccccc2O1
b) CCC(CC)C(=O)Nc1cccc(/C(C)=N\NC(=O)c2ccc(C)s2)c1
c) CCOc1ccc2nc(SCC(=O)N3CCN(C(=O)c4ccco4)CC3)sc2c1
Answer: a. O=C(N/N=C\c1ccc(Br)o1)C1COc2ccccc2O1
