Task: Answer the multiple choice question.
Query: Which drug has a 9.048\% 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: Cc1nn(C)c(Cl)c1CN1CCN(C2CCCC2)C(CCO)C1
b: C=CC(=O)NCNC(=O)C=C
c: NC(=O)c1cc(N)ccc1N1CCCCC1
Answer: b. C=CC(=O)NCNC(=O)C=C
