Answer 2

Answer: C. OH

Explanation: A radical is defined as a molecule with unpaired electrons; thus your answer is OH. However, if you want a more general definition (an atom or molecule with unpaired electrons), then OH, O and H are all radicals. Only H2O is a closed-shell species. and is therefore not a radical.
