B. 4 cm, 10 cm, and 15 cm

According to two sides, 4, and 10 cm, the third side has to be between 
10-4 and 10+4
6<side length<14

However, the side length is 15 cm, greater than 14 cm, so it is not a triangle.

Hope this helps :)

It should never be written in abbreviated form because some words are difficult to understand in abbreviated form and chances of getting confused are higher while reading.

It is better if we start writing Definition in

Arranging in alphabetical order and then writing in complete sentences.

But writing in complete sentences of any vocabulary must be first priority.

Option (C) In complete Sentences
