Final answer:
The correct word to complete the sentence is 'Its', which is a possessive pronoun without an apostrophe, indicating that the rewards belong to the sensory adventure.
Step-by-step explanation:
A possessive or ktetic form is a word or grammatical construction indicating a relationship of possession in a broad sense. This can include strict ownership, or a number of other types of relation to a greater or lesser degree analogous to it.
Most European languages feature possessive forms associated with personal pronouns, like the English my, mine, your, yours, his and so on. There are two main ways in which these can be used: Together with a noun, as in my car, your sisters, his boss. Here the possessive form serves as a possessive determiner.
The correct word to use in the sentence 'Moreover, a memorable sensory adventure can have it’s rewards' is c) Its. The possessive pronoun 'its' is used to signify belonging or association to a non-human subject without an apostrophe. In this context, 'its' refers to the 'memorable sensory adventure' having rewards, not 'it is' or 'it has', which would be abbreviated as 'it's' with an apostrophe.
