Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

All are correct. Explanations wrt Option 1) All three carbon-oxygen bond distances are about 1.28 Angstroms long. You cannot draw a Lewis structure that would suggest all three bonds are the same length. 4) Bond angle is 120 degrees as all three bonds are equal. 2) Carbon is hybridised sp2, all oxygens are equivalent. 3) resonance allows for delocalization, in which the overall energy of a molecule is lowered since its electrons occupy a greater volume, molecules that experience resonance are more stable than those that do not. These molecules are termed resonance stabilized. The stability of resonance increases with: Number of covalent bonds and Number of atoms with an octet of electrons (except hydrogen). So it shows resonance stability.
