Select the correct answer using the code given below.

• A. 1 only
• B. 1, 2 and 3
• C. 1 and 2 only
• D. 2 and 3 only

Answer 1

The correct option is B 1, 2 and 3

Explanation:

Statement 1 is correct: Global warming is linked with the spread of pathogens. Ticks and mosquitoes carrying vector-borne pathogens are increasing in population and colonising new areas.

Statement 2 is correct: Global warming increases the temperature which enhances the biophysical driving force of transpiration, thereby contributing towards increasing transpiration rates.

Statement 3 is correct: Vegetation is mostly temperature-sensitive and global warming will thus result in shifting of vegetation.
