Increased global temperatures have decreased disease incidence of the cattle, leading to their increased growth.
The correct option is A.
<h3>What is an example of growth?</h3>
A gradual increase in time, size, mass, or height is referred to as growth. An example of maturity is a rowdy teen who grew noticeably quieter in her late 20s. A boy that grows an inch taller between both the ages of 14 and 15 is an illustration of growth.
<h3>What causes growth?</h3>
Hormones created by the pituitary gland in the brain regulate a person's body's growth from the moment they are born. Growth hormone, sometimes referred to as human growth hormone, HGH, or GH, is the most crucial hormone for growth.
