Answer: In java the symbol "+" operator is used to perform string concatenation.
Explanation:
String concatenation refers to joining of two strings. So in java + is used to join strings which works provided one of the operands must be a String variable. Then it works by converting the other variable to String variable and joins the second operand to the end of the first operand.
An example of String concatenation is as follows:
int age = 10;
System.out.println("The boys age is " + age);
Output:
The boys age is 10.
here, the age is integer variable but as the phrase "The boys age is" is a String variable so it converts the age to String variable and joins both the Strings.

b. The outer subquery initiates the process of execution in a subquery.
B is correct.
Explanation:
The important feature of a correlated subquery is: It must be executed repeatedly because it depends on the value from the outer SELECT, and must execute once for every value that the outer SELECT produces.
It think it's a Nested List.
Im so sorry if this is wrong
