Answer 1

Hint: Periplaneta americana is the scientific name for the species of the American cockroach. It is the largest species of cockroach which is commonly referred to as a pest. It comes under Phylum Arthropoda, class Insecta. There are three common types of cockroach- American cockroach, Oriental cockroach, and German cockroach. They prefer the moist area to live in.

Complete step by step answer: Assertion is true but the reason is false.
Cockroaches are nocturnal, omnivorous, household pests because they are found in places where there is warmth, dampness, and plenty of organic food. Cockroaches are scavengers because they eat all types of materials, which include paper, cloth, dead animals, plants, etc.
Option B- Assertion is false and Reason is true.
The reason is true. The assertion is also true. So this option is not correct.
Option C- Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
The reason is not the correct explanation for the given Assertion because there is no relation between being a nocturnal, omnivorous animal and is acting as a scavenger.
Both Assertion and Reason are true but Reason is not the correct explanation of Assertion
Thus, the correct option is Option D- Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

Note:Nocturnal organisms are the organisms that are more active at night as compared to that of day. Most often, nocturnal species find food with the help of a sense of smell and find their mates by following pheromone trails. Omnivorous insects are the insects which can eat both animal and plant.
