Correct option is C
Step 1: Identify the sentence type and tense
· The sentence contains
a statement ("I've worked for you for five years") and
a request for a raise ("What about giving me a raise?").
·
"I've worked" (Present Perfect) changes to "he had worked" (Past Perfect).
· The question
"What about giving me a raise?" is
a polite suggestion/request and should be changed to
"asked about giving him a raise."
Step 2: Apply the conversion rules
·
Direct: "I’ve worked for you for five years," the man said to them, "What about giving me a raise?"
·
Indirect:
The man said that he had worked for them for five years and asked about giving him a raise.
Why other options are incorrect?
·
(a) "Has worked" ("Has worked" should be "had worked" for correct tense conversion).
·
(b) "Advised him to give him a raise" (Incorrect because the sentence is a request, not advice).
·
(d) "Suggested that he should give him a raise" (Incorrect because "suggest" is used for general ideas, not personal requests).
