Rearrange the parts of the sentence in correct order.
The Finance Minister, under
P-whose supervision this
Q-has not made any definite statement
R-has taken place,

The given starting phrase is "The Finance Minister, under".
This naturally connects with the relative pronoun P ("whose supervision this") to identify what happened under his authority.

This is followed by R ("has taken place,") which completes the descriptive subordinate clause ("under whose supervision this has taken place").

Finally, Q ("has not made any definite statement") provides the main predicate/verb phrase for the subject "The Finance Minister".

Therefore, the correct chronological sequence is PRQ.
