The highlighted word is used correctly in sentence I. It is used here as a noun with the meaning 'a large shop where you can buy many different types of goods'.
The highlighted word is used correctly in sentence II. It is used here as a verb with the meaning 'to put or keep things for use in the future'.
In sentence III, the usage of this highlighted word is incorrect grammatically. The phrase 'one of the' should be followed by a plural noun, whereas 'store' is a singular noun. Hence, its plural form 'stores' would be correct to use in its place.
Hence, option (a) is the answer.
