Problem statement: Answer the multiple-choice question.
Query: Which drug has a 18.675\% 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 additional words.
Options:

b: COc1ccc2occ(C(=O)c3ccc(N=C(C)N(C)C)cc3)c2c1
c: NC(=O)C1CCN(c2oc(/C=C/c3ccc(F)cc3)nc2S(=O)(=O)c2ccccc2)CC1
Answer: a. O=C(NNC(=O)c1cccc(-n2cnnn2)c1)c1ccccc1
