The answer to this question is given below in the explanation section.
Explanation:
The correct answer to this question is C i.e. String s = "apluse";
The rule or syntax of declaring string in any programming language is given below:
String variable-name = "yourString";
For declaring string variable, first, you write "String" that is a keyword of a programming languages for declaring string variables, such as int before the variable name for declaring integer variable. Then, you need to write a meaningful name of the string as a variable. After string variable name, you need to put the equal operator and then write the string in double quotation("") marks and after that put the instruction terminator that is ";".
So, according to this syntax, option C is correct.
While other options are not correct because:
In option a, string is not encapsulated in double quotation. Option B does not have varaible type such as String and Option E does not have variable name and its value also. So, only option C is correct and all other except C are incorrect.
Answer:
In a split system, the compressor condenses and circulates the refrigerant through the outdoor unit, changing it from a gas to a liquid. The liquid is then forced through the indoor evaporator coil or cooling compartment. The indoor unit's fan circulates the inside air to pass across the evaporator fins.

(hope this helps)
In C, you deal with a string always via a pointer. The pointer by itself will not allocate memory for you, so you'll have to take care of that.
When you write char* s = "Hello world"; s will point to a "Hello world" buffer compiled into your code, called a string literal.
If you want to make a copy of that string, you'll have to provide a buffer, either through a char array or a malloc'ed bit of memory:
char myCopy[100];
strcpy(myCopy, s);
or
char *myCopy;
myCopy = (char*)malloc( strlen(s) + 1 );
strcpy(myCopy, s);
The malloc'ed memory will have to be returned to the runtime at some point, otherwise you have a memory leak. The char array will live on the stack, and will be automatically discarded.
Not sure what else to write here to help you...
