Answer 1

1.

Answer to question 1, according to my knowledge is the option 'b'. String canine;

As we know in Javascript the variables are declared using 'var' keyword and assignment of variables means storing data in the variables using '=' operator.
At the time of assignment of the variables, the data type is identified by the javascript.
As the variables in javascript can store more than one data type in a program.
Hence the datatypes are identified at the time of data assignment.

Answer to this question is an option 'd',

As in this, we define the datatype and then give the name of the variable and then the semicolon,
Because it is the correct syntax for declaring a string variable.
