From passage=>"If actors fail to make it big, they have only themselves to blame."
B. Performers who master a craft, scale heights
>> This does not talk about how you show yourself big. It just talks about mastering a craft. This will not guarantee to scale high.
D. Nothing can take anything from you, if you don't allow it to happen
>>Passage talks about who fail to make it big. This option fits well with the 'fail to make it = don't allow to happen'
D is the best fit. Hope it helps.
