Identify the tense in which the following sentence is written.
He has been speaking in a loud voice.

Correct option is C

Correct tense: (c) Present Perfect Continuous
Identification (highlight):
• Structure: has/have + been + V-ing → “ has been speaking”
• Shows action that started earlier and is continuing/relevant up to the present.
Grammatical Rule (English):
• Present Perfect Continuous = has/have been + verb-ing
व्याकरणिक नियम (Hindi):
• Present Perfect Continuous की रचना has/have + been + verb-ing होती है; यह लगातार जारी/हाल तक चल रही क्रिया दर्शाती है।
Hence, option (c) is the correct answer.
