‘Attacked on him’ is the incorrect form of phrasal verb that needs to be replaced with ‘Attacked him’ to make the sentence correct. This is because; ‘Attack’ is not followed by any preposition. Thus, the correct sentence would be, ‘That Brutus, who was his trusted friend had attacked him caused heartbreak to Julius Caesar’.

The relative pronoun acts as the subject or object of the relative clause. It replaces words like she, he, him, her, they, them etc.

It is, therefore, wrong to repeat the pronoun in the relative clause.

Hence, the correct sentence is Shreya, who is my best friend, is a singer.

The phrase ‘was courted’ needs to be replaced with ‘courted’ to make the sentence grammatically and contextually correct. Thus, the correct sentence would be, ‘He courted arrest in order to protest against corruption among the government servants’.
