An adsorption type desiccant works by adhering moisture from the air to its surface, rather than absorbing it into its structure as some other types of desiccants do. This process allows it to effectively remove humidity from the surrounding environment.

While it is true that some operational aspects of adsorption desiccants may involve heating for regeneration, they typically operate effectively at ambient temperatures, making high-temperature operation unnecessary for their function. Moreover, these desiccants require regeneration to restore their moisture-absorbing capacity, which is a crucial part of their operational cycle.

Therefore, the statement that all answers apply does not hold, as not every aspect mentioned in the choices correctly describes the functionality of adsorption type desiccants. In summary, the correct understanding would be recognizing that adsorption desiccants absorb moisture but require regeneration and do not typically operate at high temperatures, leading to the conclusion that the correct choice should reflect accurate attributes of these devices, which are not encapsulated by the option implying all statements are true.
