D Correct answer
Explanation

Explanation for (1): The correct pronoun to use for persons is 'who'. The antecedent is 'suspicious minded guards'. 'That' is used as a pronoun either for a combination of persons and non-persons or when the information it refers to is vital to the meaning of the sentence. Neither is the case here.

Explanation for (2): 'Treasure' is a collective noun so it does not take an 's' in the plural form. 

Explanation for (3): The option does not correct the pronoun error and also has a preposition error.  'Amongst' is correctly used before a vowel sound; otherwise 'among' is used for more than two persons or things. 
Justification for (4): The correct pronoun to use for persons is 'who'. The antecedent is 'suspicious minded guards'.  This option maintains consistency in tense, correct noun use and correct pronoun. Explanation for (5): The option changes the simple past 'drove' to 'had driven'. This is inconsistent with 'left' and 'requested'.
