Question

Select the appropriate option to fill in the blank:

We need to be careful to ensure that our project is on the right __________.

• A. route
• B. road
• C. track
• D. way

Answer 1

Answer: (C)

track

Option C: 'Track' is a 'course of action or line of thought'. It agrees to the given sentence: 'we need to be careful to ensure that our project is on the right course of action'.
Hence option C is correct.
'Route' means 'a way or course taken to reach a destination'.
'Road' is a course or direction taken or followed
'Way' is a course of travel or a route taken to reach a place.
Even though all of these words mean the same as 'track', they will not be used here. This is because 'on the right track' is a set phrase, and if we replace the word with 'way', 'route' or 'road', the phrase does not produce the desired meaning.
Hence options A, B and D are incorrect.
