• A. A- 3, B- 1, C- 4, D- 2
• B. A- 1, B- 2, C- 3, D- 4
• C. A- 4, B- 1, C- 3, D- 2
• D. A- 2, B- 3, C- 4, D- 1

Answer 1

The correct option is A A- 3, B- 1, C- 4, D- 2

Seismonasty: Nastic movement in response to shock, especially the rapid folding of the leaflets of the sensitive plant due to changes in the turgor pressure caused by vibration.

Thermotaxis: Thermotaxis is a behavior in which an organism directs its locomotion up or down a gradient of temperature.

Chemotaxis: Movement of cells or organisms to chemicals, whereby the cells are attracted (positive chemotaxis) or repelled (negative chemotaxis) by substances exhibiting chemical properties.

Hyponasty: Increased growth of the lower surface of a plant part, resulting in an upward bending of the part.

Therefore, the correct answer is option A.
