Answer 1

Solution

4.

Explanation

An absolute path is defined as specifying the location of a file or directory from the root directory(/). In other words,we can say that an absolute path is a complete path from start of actual file system from / directory.

thats why

/home/max

/home/max/literature/promo

is absolute reference

---

Relative path is defined as the path related to the present working directly. It starts at your current directory and never starts with a / .

correspond/business/milk_co

~/marketing/print

..

is a relative reference
