I had been asked this question in an online quiz.

This is a very interesting question from Data Types in portion Nuts and Bolts and Getting Data In and Out of R Programming

Answer 1

Right choice is (b) Lists

The explanation: To extract a sublist, we use single brackets. There are a number of ways of accessing the first component of a list. There are also many functions within R that produce a list as output. Examples of these functions include spline(), density() and locator().
