Explanation:
The statement that Crusoe most likely agree with would be that 'irrespective of the life plans that one has made, he/she must pursue the one that offers the best accomplishment' at the given moment and that too with 'rational planning and foresight.' Dafoe reflects that <u>'one must give value to his/her insights and create a life of their own through hard-work and diligence</u>. He aims to promote self-sufficiency and 'freedom of conscience.' Thus, <u>option D</u> is the correct answer.
