What will be the output if we replace the line $num = preg_grep(“/[0-5]/”, $number); with $num = preg_grep(“/[0-5]/”, $number, PREG_GREP_INVERT);?

A. Array([0]=>0 [1]=>1 [2]=>two [3]=>three [4]=>four [5]=>5)

B. Array([2]=>two [3]=>three [4]=>four)

C. Array([1]=> 1)

D. Array([0]=>0 [5]=>5)

Answer: Option B

Solution(By Examveda Team)

When we include PREG_GREP_INVERT, this will invert our data, so instead of outputting numbers it will output our non-numeric values.
