Solution

The correct option is C A is correct but R is incorrect
The plants yield a milky suspension of crude rubber called latex.
Latex is often described as the sap of the Hevea tree, a milky sticky substance.

The sap runs deeper inside the tree, beneath the cambium.
Latex runs in the latex ducts which are in a layer immediately outside the cambium. This highlights the skill of the tapper.

If the cambium is cut, then the tree is damaged because the cambium is where all the growth takes place.

The latex contains about $60 %$ of rubber and $40 %$ of other substances (water, proteins etc).

Assertion (A) is correct. Reason (R) is incorrect. Option C is correct.
