Class : Class 1

The correct answer is A.

Both plants ‘c’ and ‘d’ bear fruits. This means they are flowering plants as only flowers change into fruits. Plant ‘c’ grows in water i.e., it is an aquatic plant but plant ‘d’ does not grow in water thus, it is a nonaquatic plant. Hence 'W' and 'X' represent plant ‘c’ and ‘d’ respectively.

A is the correct answerWhen food is taken in the mouth, it is chewed and gets mixed with saliva secreted in the mouth (R). Once swallowed, the food moves through the oesophagus into the stomach where churning and digestion of food with digestive juices occurs (Q). The semi-digested food then moves into the small intestine where complete digestion as well as absorption of nutrients occur (S). From the undigested food, the water is absorbed in the large intestine (P). After this, the undigested food is expelled through the anus in the form of faeces (T).
