Who among the following, after watching the performance of William Shakespeare’s play, A Midsummer Night’s Dream, observed that “it is the most insipid, ridiculous play that I ever saw in my lifE”

The correct option is Samuel Pepys.

Samuel Pepys (1633–1703) was an English administrator and Member of Parliament, now famous for the detailed private diary he kept from 1660 until 1669. His diary provides a valuable first-hand account of daily life, historic events, and cultural activities in Restoration London.
On September 29, 1662, Pepys attended a performance of William Shakespeare's romantic comedy A Midsummer Night's Dream at the King's Theatre. In his diary entry for that day, he recorded a famously harsh critique of the play, writing:
"...to the King’s Theatre, where we saw ‘Midsummer Night’s Dream,’ which I had never seen before, nor shall ever again, for it is the most insipid ridiculous play that ever I saw in my life."
