• A. Short Day Plants
• B. Long Day Plants
• C. Day- neutral plants
• D. All of the above

Answer 1

The correct option is A Short Day Plants

Species growing on the high altitude are predominantly short day plants due to the long duration of winter existing on mountain regions. These plants require a relatively short daylight period (8-10 hrs) and a continuous dark period of about 14-16 hours for subsequent flowering. These plants are also known as long night plants. For example, rice, coffee, soybean, tobacco and Chrysanthemum.

So, the correct answer is 'Short Day Plants'
