Option B is the correct answer because ‘chopped’ means ‘cut
into pieces with a knife or axe’. It is mentioned that the axes were picked up
so ‘chopped’ is the most appropriate word to describe the cutting of the thorny
bushes.
Option A is incorrect because ‘slice’ means ‘thin, broad piece’. Slice is generally
used for food items hence it is not the appropriate word for this sentence.
Option C is incorrect because ‘pulled’ means ‘to withdraw or to remove
something with force’. Although the meaning is similar, ‘pulled’ is not an
appropriate word grammatically.
Option D is incorrect because ‘scratched’ means ‘mark with something sharp’. It
is not the correct word to describe the cutting of the thorny bushes.
