Answer 1

Hint: The plants that begin flowering when the days are shorter than their critical day length are known as short-day plants. These types of plants require a long period of darkness and a short period of light to flower. Some Examples of short-day plants are rice, tobacco, chrysanthemum, cotton.

Complete answer:
Option (A) is Maize. It is also known as corn which is a cereal grain. It was first domesticated by indigenous peoples in southern Mexico about 10,000 years ago. It is not a day-neutral plant.

Option (B) is radish
It is an edible root vegetable, as we all know. It belongs to the family Brassicaceae. It was domesticated in Asia prior to Roman times. Radishes are grown and consumed throughout the world in the form of raw and crunchy salad vegetables with bite.

Option (C) is Chrysanthemums are also called mums or chrysanths. They are flowering plants of the genus Chrysanthemum and family Asteraceae. They are native to East Asia and northeastern Europe. Most species usually originate from East Asia and the center of the diversity is in China. There exist countless horticultural varieties and cultivars.

Option (D) is Wheat
Wheat is a grass that is widely cultivated for its seed, a cereal grain that is a staple food for the entire world. The genus Triticum is made by many species of wheat together but the most widely grown is termed as common wheat (T. aestivum)

Hence, The correct answer is option (C).

Note: Chrysanthemum is a short-day plant, which means that long nights (11 to 12 hours of darkness or a longer time, depending on the cultivar) are required for the rapid flower initiation and its development. Sometimes blackout systems are also used to induce the flowering before the plants and normally would under naturally the most shortening days.
