Answer:
The correct answer is Option (1) three_com
Explanation:
There are a few rules you need to keep in mind while naming any variable, which are as follows:
- The first letter of any variable name should be either a letter of an alphabet or an underscore. For example, helloWorld or _helloWorld.
- No special characters (except underscore obviously) or spaces in between the name are allowed. For example, <em>hello&world</em> or <em>hello world</em> are not valid names.
- The first letter of the variable name should not be a number.
Now look at all the options given:
Option-1 (three_com): The name starts with the letter <em>t</em> of an alphabet and there are no spaces or special characters in it except an <em>underscore</em> (which is acceptable). Therefore, this option is correct.
Option-2 (3com): The name starts with a number. Not allowed.
Option-3 (3_com): The name starts with a number. Not allowed.
Option-4 (ampersand&): The name has a special character <em>&</em> in it, which is not allowed as per the aforementioned rules.
Hence, the correct answer is option (1) <em>three_com</em>.
