Assertion : `FeI_(3), CuI_(2), PbI_(4)` do not exist but `FeF_(3), CuF_(2), PbF_(4)` exist.
Reason : `F_(2)` having highest oxidising power whereas `I_(2)` having least oxidising power among halogens.

Options

A. If both assertion and reason are true and reason is the correct explanation of the assertion.
B. If both assertion and reason are ture and reason is not the correct explanationof the assertion.
C. If assertion is true but reason is false.
D. If assertion is false but reason is true.

Answer

B

Explanation

`Fe^(3+), Cu^(2+)` and `Pb^(4+)` are the strong oxidising ions which react with reducing ion `I^(-)` to produce `I_(2)`, e.g.,
`Pb^(4+) + 4 I^(-) rarr Pbl_(2) + I_(2)`
