Task: Answer the MCQ question.
Query: Which drug exhibits a 11.003\% 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(NCc1ccc(Cl)cc1)c1nccnc1CO
[b] CN1CCN(c2cc(-c3cc(O)c4ncccc4c3)ccn2)CC1
[c] COc1ccc(/C=N/n2cnc3c(sc(=S)n3-c3ccccc3)c2=O)cc1
Answer: a. O=C(NCc1ccc(Cl)cc1)c1nccnc1CO
