The correct answer is can be reversed with no net change in either system or surroundings
Reversibility is a property that expresses the possibility of making the physical processes run in the opposite direction, infinitely varying the conditions that cause them.
The concept of reversibility has great importance in thermodynamics (in the foundation of its second principle), since it is the only type of processes that use the least amount of energy possible; thus, reversibly, the physical processes give their greatest performance.
In practice, it is not possible to obtain a completely reversible evolution of a process, because for this to happen, it should take place in an infinitesimal way, and, therefore, take an infinite time to complete. However, in order to obtain the highest possible efficiency, motors, machines, etc., are designed in such a way that the processes carried out on them are extremely similar to reversible processes.
Use the isdigit method to see if a character is a numeric digit character.
A positional numeral system uses a single symbol, a numerical digit, to represent numbers. It is frequently abbreviated to "only digit." Examples are "2" and "25." The word "digit" derives from the fact that the ten fingers (Latin: digiti) on each hand correspond to the ten symbols of the conventional base-ten numeric system, or decimal (Old Latin: decem, meaning "ten") digits.
The absolute value of the base determines the required numerical digit for a given numeral system with an integer basis. For instance, the base-10 decimal system requires ten digits (0 through 9), whereas the base-2 binary system only needs two digits (0 and 1).

B . Plains , I do not know the explanation
Income is not the only factor that causes a shift in demand. Other things that change demand include tastes and preferences. the composition or size of the population is a reason. the prices of related goods, and even expectations. It’s important for people to recognize because as demand increases, the available supply also decreases. But if supply decreases, prices may increase. Supply and demand have an important relationship because together they determine the prices of most goods and services.

The baby is displaying a behavior of habituation in which a
person who shows habituation likely shows disinterest to a certain condition or
he or she likely no longer responds or has stopped responding to a certain
condition or stimulus in which the baby displays.
