Answer 1

Hint: C) Monarch Butterfly
The insects fall under phylum Arthropoda and constitute the largest community of organisms on the planet. They are characterized by jointed appendages, three pairs of legs (generally), and range from small sizes like ants and mosquitos to large like beetles. Plenty of diversity is found in this class. Insects are found both in aquatic and terrestrial habitats.
Centipedes, housefly and cockroaches are common pests found in households. Monarch butterflies are found in North and South America and the Caribbean regions. It is referred to as the “King of butterflies”.

Complete answer:
Monarch butterflies are the most beautiful species of butterfly. The color of this butterfly is bright orange and black. This makes it look beautiful in the daylight sky.
The monarch butterfly has 12000 eyes that help it to practically see in every direction. These butterflies have two types of eyes- Simple and Compound.
The simple eyes are single-chambered and used to detect the brightness of light. The compound eyes are the major eyes that are used mainly for normal vision.
In addition to this, these butterflies are also able to see ultraviolet light which is not visible to humans.

Note:
Cockroaches and House Flies also have a complex type of vision known as mosaic vision. They can also see in various directions at a time.
The cockroach consists of ommatidia which are the functional unit of vision. A compound eye of a cockroach has 2000 such ommatidium that together help to form a larger image of overall surrounding but with less clarity and resolution.
