Rather than a single address, you can refer to an array using their first (top/left) and last (bottom/right) addresses separated by a
exclamation
colon (: )
asterisk (*)
period

Period(.)

Explanation:

Option A is rejected because exclamation mark is not used in programming languages to reference an array but it is used as Operator to mark if the value is NOT

For example

if(x!=2)

this statement check if the x variable is NOT EQUAL TO 2.

Option B is rejected because it is used in objects for the languages which use them as key value pairs

for example :

IN java script objects are like :

const person = {

name : 'Asad',

id : 1

}

Option C is rejected because it is used to slect all the records of some data structure.

for example in database to select all the records of a row we write:

select * from table_name where id=1;

Option D is selected because Period references to the nested values of the array if the index is the parent value.

is this supposed to be a question ?

the answer is you.
