Task: Answer the multiple-choice question.
Query: Which drug has a 18.531\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a O=C(CSc1nc2ccccc2c(=O)n1-c1ccccc1)N1CCN(CCO)CC1
b O=C(O)c1cc2c(=O)c3ccccc3oc2nc1C(F)(F)F
c CCc1cc2cccc(C)c2nc1SCC(=O)Nc1cc(C)on1
Answer: a. O=C(CSc1nc2ccccc2c(=O)n1-c1ccccc1)N1CCN(CCO)CC1
