↪ $<b>Typing$ -

$add = $add+$add

because $add += $add

doubles the value of $add and so does $add = $add+$add if initially $add = $add = $add + 1

C.$add = $add + 1✔✔

Answer 2

Option b is the correct answer. Here $add = $add +$add is equivalent to $add += $add

• += is an addition assignment operator.
• += operator adds up or concatenate the value or string respectively of the right hand operand to assign a new value or string within the variable.
• Here, if $add stores numerical value then $add += $add is equivalent to $add = $add +$add or $add = $add + 1 (i.e, option b or c both).
• If $add stores string then $add += $add is equivalent to $add = $add +$add (only option b).
• So, as a whole, option b is much more appropriate in this case.
