…… all intents and purposes, the manager is the master of the firm. A. in B. upon C. with D. to

in
upon
with
to

The correct answer is: to.

The phrase “to all intents and purposes” means “in every way that matters” or “for all practical purposes.” In this sentence, it is used to emphasize that the manager has complete control over the firm.

The other options are not as appropriate in this context. “In” could be used to mean “inside” or “within,” but it does not make sense in this sentence. “Upon” could be used to mean “on” or “based on,” but it does not make sense in this sentence. “With” could be used to mean “together with” or “in addition to,” but it does not make sense in this sentence.

Here are some examples of how the phrase “to all intents and purposes” can be used in other sentences:

  • To all intents and purposes, the two companies are now one.
  • To all intents and purposes, the war is over.
  • To all intents and purposes, the patient is cured.
