I believe the correct answer from the choices listed above is option 2. An elongated hill that is composed of unsorted sediments deposited by a glacier is called a drumlin. These occur widely within the moulded and streamlined scenery of the central lowlands of Scotland. 
Hope this answers the question. Have a nice day.

Answer:

(2) a drumlin

Explanation:

  • The word drumlin is taken the form an Irish word droimnín, recorded in 1833, its is a classical elongated hill and is composed of the glaciers depositional features and has unconsolidated matters formed by continuous and reverse depositions by the glaciers.
