Answer:
The phrase which would choose if two things or ideas are contrasted is:
c. on the other hand
Step-by-step explanation:
Option c is the correct option. All the other three are incorrect options. The phrase 'as a result' is used to signify the conclusion of an idea or concept. The phrase 'leads to' points out to the next level of the progression of the idea or concept. The phrase 'in the meantime' defines two things working simultaneously.
