Assertion (A) : The plants yield a milky suspension of crude rubber called latex
Assertion (A) : The plants yield a milky suspension of crude rubber called latex. Reason (R) : The latex contains about \( 85 \% \) rubber
- A. Both A and R are correct and R is the correct explanation of the A
- B. Both A and R are correct but R is not the correct explanation of the \( A \)
- C. A is correct but R is incorrect
- D. A is incorrect but R is correct
Step-by-step solution
The assertion is true: plants like the rubber tree produce a milky suspension called latex. However, the reason is false because natural rubber latex typically contains only about 30-40% rubber, not 85%. The remaining portion is water and other substances.
