The boiling points of diatomic halogens are compared in the table. Boiling Points of Diatomic Halogens Molecule Boiling Point F2 −188 °C Cl2 −34 °C Br2 59 °C I2 184 °C Which of the following statements best explains the trends in boiling points?

it's filtration, but this is an assumption so my apologies if i got this

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
