Answer: (A) Advanced age
Explanation:
Pneumonia is a kind of infection that causes the inflammation of the air sacs of lungs. This results in the deposition of the air sacs with pus or fluid, which results in symptoms of fever, pus, cough and difficulty in breathing. A variety of organisms such as fungi, viruses and bacteria can cause pneumonia.
Pneumonia can affect any human being but severe symptoms develops in infants, people of old age, and people suffering from diseases. As these people are likely to have weak immune system.
Among the options given, advance age is the correct option, this is because of the fact that the person is obese 85 year old although his diet is healthy but due to lack of immunity in the older age the risk of development of pneumonia will be the greatest.

Delta is a type of fibre that transmits signals that are interpreted and perceived as pain.
<h3>
Delta fibres</h3>
A delta fibres (also known as A fibres) are a type of sensory fibre. They respond to cold and pressure stimuli, and as nociceptors, their stimulation is perceived as fast/first pain input. Because they are thinly myelinated, they transmit impulses quicker than unmyelinated C fibres but slower than other, thicker myelinated "A" class fibres.
Structure
They have myelinated axons that are thin (2 to 5 m in diameter) and have a moderate conduction velocity, or speed at which a nerve signal moves (2 to 30 m/s). These nerve fibres make up the afferent portion of the reflex arc that causes the body to "draw away" from noxious stimuli because they are linked to acute (sharp) pain (e.g. retracting your hand away from a hot stove). A part of A fibres is also linked to pressure and temperature perception (also known as "cold receptors" in mammals). Contrarily, slow-conducting, unmyelinated C fibres convey gradual, scorching pain.
