Answer:
The proper synonym for the expression in italics is Option C: survive .
Step-by-step explanation:
Italicized word “Get by” means “to manage with difficulty to live with” or . It also means to survive or cope up. The sentence means that “Do not worry about me, I will be able to cope up or get on”.
Use of option A is ‘live’ will not fit in the meaning of the given sentence. Option B ‘stay’, means to remain at one place, which also doesn’t fit in the sentence. So, option A and B are incorrect to be used as a synonym for ‘get by’ and the correct answer is Option C.
