A. is changing
Feedback We use the present continuous to describe things which are in the process of changing, i.e. trends. With this use of the present continuous, we often use time expressions like ‘now’, ‘nowadays’, ‘at the moment’, etc. We form the present continuous with ‘am’, ‘is’ or ‘are’ + the ‘ing’ form of the main verb; e.g. watching, going, eating, smiling etc.
