Assertion : CuSO(4).5H(2)O on heating to...

Assertion : `CuSO_(4).5H_(2)O` on heating to `250^(@)C` losses all the five `H_(2) O` molecules and becomes anhydrous.
Reason : All five `H_(2) O` molecules are coordinated to the central `Cu^(2+)` ion.

A

(1) Assertion is true, Reason is true, Reason is a correct explanation for Assertion

B

(2) Assertion is true, Reason is true, Reason is not a correct explanation for Assertion.

C

(3) Assertion is true, Reason is false

D

(4) Both assertion and Reason are false.
