Answer 2

Option (A) Array is the right answer. Using array same operations can be performed on various elements of a similar type.

• An array helps the programmer to keep unlimited data of one type.
• And all the elements are kept in continuous memory location only.
• To define the string values using data type is the String.
• If- then is used as a conditional statement.
• While is also a loop whose purpose is to execute a group of code based on a condition.
• Since an array contains more than one data of a unique type it also allows to perform the same operation on all of the elements in the array.
