D. Pupa

Answer 1

Hint: Cockroach is an insect which belongs to the largest phylum Arthropoda. Cockroaches have a small head and a flattened body. They are considered as pests as they carry pathogenic microbes which can spread diseases. They are mostly present in dark and moist places.

Complete answer:
Cockroaches are insects which belong to the phylum Arthropoda. There are about four thousand species of them. They generally prefer living in dark and moist conditions and usually come out at night and hence are nocturnal. They can be infectious and a cause of various diseases in humans as they carry pathogenic microbes. They have a brownish black body with a small head and flattened body. They are also present in yellow, green, and red color in tropical regions. The body of a cockroach is divided into a head, thorax and abdomen. Their entire body is covered with a hard chitinous exoskeleton.
Understanding the life cycle of a cockroach:
The life cycle of cockroaches is divided into three developmental stages, the egg, the young nymph and the adult cockroach. As the eggs hatch, the young cockroaches known as nymphs are developed. They are very small in size and are white in color. These nymphs go through several stages of molting during which their bodies become soft as they cast off parts of their body. With each molting process, the nymph grows in size and the color of it gradually changes to brown. Molting is carried out until the nymph is developed into an adult cockroach. This process of molting can take a week to several months, depending on the species of the cockroach and the environmental conditions.

Thus, the correct answer to this question is option B – nymph.

Note:
Cockroaches are a means of spreading diseases in humans as they live mostly in sewage and hence carry pathogenic bacteria. They contaminate the food with their excretory product, saliva, or just by crawling on the food. They can cause diarrhea, dysentery, typhoid, etc., in humans.
