Answer:
The correct answer is- a. absolute
Explanation:
The lowest intensity of any stimulus which can be noticed by a person is called the absolute threshold. So here when jack is camping in the woods he noticed very faint light which can be barely seen by him which shows that it is the lowest intensity of light which he can see so here the light is right at jack's absolute threshold.
The absolute threshold varies from individual to individual and it can also vary with in the individual due to change in attention, awareness, etc. Therefore the correct answer is absolute.
