What is the result of this echo statement ?

it gives this compilation error :
String found where operator expected at *.pl line 5,
(Do you need to predeclare echo?)
syntax error at *.pl line 5, near "echo "a > b
Execution of *.pl aborted due to compilation errors.

It's not an option, i am confused myself, but the question i got had four options : 1- Puts '"a' in the file 'b'".
2- Shows 'a > b'.
3- Shows "'a > b'".
4- Puts 'a in the file b'
