These questions consist of two statements each, printed as Assertion and Reason. While answering these questions you are required to choose any one of the following four responses:
Assertion: `[Ti(H_2O)_6]^(3+)` is coloured while `[Sc(H_2O)_6]^(3+)` is colourless.
Reason: d-d transition is not possible in `[Sc(H_2O)_6]^(3+)`.

Options

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

Answer

B

Explanation

Both `[Ti(H_(2)O)_(6)]^(4+) and [Sc(H_(2)O)_(6)]^(3+)` are colourless, due to absence of free electrons in 3d subshell.
