• Pharynx: Pharynx is part of the digestive system as well as the respiratory system because it carries both food and air.
• Larynx: This is also known as the voice box as it is where sound is generated. It also helps protect the trachea by producing a strong cough reflex if any solid objects pass the epiglottis
• Trachea (Wind Pipe): It carries air from the throat into the lungs. The inner membrane of the trachea is covered with cilia

Statement 1, 2 and 3 are correct:

Gamma rays – also known as Gamma Radiation. It is the EM radiation with the highest frequency. They are produced by the decay from high energy states of atomic nuclei (gamma decay). Gamma radiation can be produced artificially similar to the process of X-ray generation. Gamma rays have frequencies higher than 10 exahertz (>1019). Gamma rays are known to kill cells. They are increasingly used to kill cancerous cells.

Statement 4 is Incorrect

Gamma radiation is ionizing radiation.

• Ionizing Radiation:  It  is  radiation  composed  of  particles  that  individually  carry  enough energy to liberate an electron from an atom or molecule without raising the  bulk material to ionization temperature.

Vitamin D is one of many nutrients our bodies need to stay healthy. Among the vitamin’s main functions, it helps the body:

• Absorb calcium. Vitamin D, along with calcium, helps build bones and keep bones strong and healthy.
• Block the release of parathyroid hormone. This hormone reabsorbs bone tissue, which makes bones thin and brittle.

All are correctly matched

Statement 1 is wrong as in osmosis solvent molecules moves from low concentration solution to higher concentration solution through a semipermeable membrane.
Statement 2 is also wrong as in reverse osmosis external pressure is applied to the higher concentration solution. SOlvent in this case move from concentrated solution to dilute solution. External pressure applies is above the osmotic pressure.
