  A-i-3, B-ii-2, C-iii-1, D-iv-4
• B. A-i-1, B-iii-2, C-ii-4, D-iv-3
• C. A-i-2, B-iii-1, C-ii-4, D-iv-3
• D. A-ii-1, B-iii-2, C-iv-3, D-i-4

Answer 1

The correct option is C A-i-2, B-iii-1, C-ii-4, D-iv-3

$\bullet$ Squamous epithelium are thin, flat and delicate cells. These single-layered cells have semipermeable membranes through which transportation of substances occur and they are mainly found in oesophagus, mouth linings, blood vessels, lung alveoli, etc.
$\bullet$ Heart muscles are called cardiac muscles. They help in pumping blood from the heart to other parts of the body.
$\bullet$ Nervous tissue conducts nerve signals (impulses) across the animal body and hence helps in co-ordination of life processes.
$\bullet$ The outermost cells in a plant structure is composed of epidermal cells. Structures like stomata are found in these cells. The stomatal openings helps in the exchange of gases and prevents loss of excess water.
