Task: Answer the MCQ question.
Query: Which drug exhibits a -0.891\% 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:
a O=S(=O)(NC1CCCC1)c1cc(F)ccc1F
b CC1C=CC(C)C(C(=O)O)C1C(=O)O
c CCc1nnc(NC(=O)CSc2nnc(-c3ccc(S(=O)(=O)N(CC)CC)cc3)n2CC)s1
Answer: a. O=S(=O)(NC1CCCC1)c1cc(F)ccc1F
