The number of correct options is
(a) `1^(Theta) gt Br^(Theta) gt CI^(Theta) gt F^(Theta)` (polarisability)
(b) `Li^(o+) gt Na^(o+) gt K^(o+) gt Rb^(o+)` (polarisation power)
(c ) `H_(2)Ogt H_(2)S gtH_(2)Se gtH_(2)` Te (order of b.pt)
(d) `H_(2)^(Theta) lt H_(2)^(o+)` (order of stability) .

If sin^(2)theta gt cos^(2) theta then

In the reaction I_(2)+2OH^(Theta)rarr I^(Theta)+IO^(Theta)+H_(2)O I_(2) is

In the reaction I_(2)+2OH^(Theta)rarr I^(Theta)+IO^(Theta)+H_(2)O I_(2) is
