This term describes two or more arrays that hold related data, and the related elements in each array are accessed with a common subscript.

a. synchronous arrays
b. asynchronous arrays
c. parallel arrays
d. two-dimensional arrays

Option (c)

Explanation:

Parallel arrays are those arrays which are used to store some records which needs more than one array to hold a entry but are interrelated and should be accessed by same index number. As they are of different data types so can't be stored as multi-dimensional array or matrix. Then parallel array comes to rescue. For example : Details of a student.

Name, age and ID of a student needs to be stored. So, three arrays can be made and each entry should be accessed by same index number.
