Answer :
The phrase from the passage which most clearly shows Crusoe's preoccupation with mastery (c) Undoubted right of dominion.
Explanation:
It was a merry reflection, which I frequently made, how like
a king I looked. First of all, the whole country was my own
mere property, so that I had an undoubted right of
dominion.... It was remarkable, too, I had but three
subjects, and they were of three different religions: my man
Friday was a Protestant, his father was a Pagan and a
cannibal, and the Spaniard was a Papist. However,
allowed liberty of conscience throughout my dominions
From the above Passage we can see Crusoe assumption about the similarities he has with a king, because he considers the whole country, as his property and he allows his people to follow different religions and beliefs,(his 3 subjects are all of different religion) by saying that he has the "undoubted right of dominion" over his land, he demonstrates his preoccupation with mastery.
Answer:
It is C. Undoubted right of dominion
