How to distinguish between past perfect and present continuous perfect here? I looked at "recognised" which was in simple past and hence the fight for that recognition would logically occur before it and hence went with A.
I mean, what makes us think that Mumbai-born Ayyadurai isn't already recognised?
Maxximus generisUnderstanding the intended meaning is key to solving this question; the intended meaning of the crucial part of this sentence is that Ayyadurai began fighting to be recognized as the primary inventor of email and continues to do so; the sentence indicates that this battle has not concluded,
as it mentions that Tomlinson is widely recognized as the inventor of email, meaning Ayyadurai is still not recognized as such. • The present perfect continuous tense (marked by “has/have been”) is the correct tense to refer to actions that started in the past and continue into the present.
• The past perfect tense (marked by the use of helping verb "had") is used when a sentence contains two actions in the past; the helping verb "had" is used with the action in the "greater past".
• The past perfect continuous tense (marked by the use of helping verb "had/have been") is only used when a sentence contains two actions in the past and one action is in the greater past as well as continuous in nature; the helping verb "had been" is used with the action that is in the greater past and continuous in nature.
• The simple past tense is used to refer to actions that concluded in the past.
Hope this helps.
