  2. Both Statement I and Statement II are true
  3. Statement I is true but Statement II is false
  4. Both Statement I and Statement II are false

Answer

(3) Statement I is true but Statement II is false

Solution

O3: resonance hybrid [figure] [figure]

Both O-O bonds 128 pm, between 121 pm (double) and 148 pm (single) I true

Intermediate length is due to resonance, not "solely" lone pair repulsion II false
