Directions: Fill in the blanks in the following sentences with the correct…

Solution The correct answer is 'that'.

Key points:

• Use 'that' when referring to things (non-people) in restrictive relative clauses that identify which item is meant.

• Use 'who' for people when they are the subject of a relative clause.

• Use 'whom' for people when they are the object of a verb or preposition; it is not appropriate here.

• Use 'which' for things, but it is commonly used in non-restrictive clauses (often set off by commas). In restrictive clauses like this proverb, 'that' is preferred.

Examples:

• All that glitters is not gold.

• All who are interested can join now.

Final note: In this sentence 'that' correctly links the noun 'all' (referring to things) to the relative clause. Therefore the complete sentence is: All that glitters is not gold.
