D. var txt = new Array="tim","kim","jim"​

Answer 1

JAVASCRIPT ARRAY

Explanation:

var txt = new Array("tim","kim","jim")

is the correct answer according to javascript syntax

the entire array is stored in variable valled txt  

so

var txt is the variable decleration suntax

new Array() is the initiation of new array by creating new object

coming to option 2

var txt = new Array:1=("tim")2=("kim")3=("jim")

Array wont take the parameters like this in the option 2

1=("tim")2=("kim")3=("jim")

Generally this type of syntax is used when passing as arguments to the functions

Coming to option1

new Array(1:"tim",2:"kim",3:"jim")

the Array wont accept key and value pairs as input and it can not store it  

In other option

var txt = new Array="tim","kim","jim"

the array decleration is not grouped into a parenthesis

so it won't take entire array it just take the first element after “=” sign
