Which of the following statement (s) are incorrect?

1.	Which of the following statement (s) are incorrect?
Answer» Photons having energy 400 kJ will BREAK 4 mole bonds of a molecule `A_(2)` where A-A bond dissociation energy is `100kJ//"mol".` Two bulbs are emitting light having WAVELENGTH `2000"Å" "and" 3000"Å"` respectively. If the bulbs A and B are 40 watt and 30 watt respectively then the ratio of no. of photons emitted by A and B per day is `1/2`. When an electron make transition from lower to higher orbit photon is emitted. 4 eV is SUFFICIENT to excite an `e^(-)` from ground state of H-atom. Answer :a,b,C,d
