Explanation:

Coherence in grammar is a characteristic that indicates that the writing is expressing exactly what was meant to be expressed following a structure and using correct language that allow everybody to understand it clearly. For sentences to be coherent, they need to use correct language and to follow its structure: subject + verb + predicate (the last could be object, adjective, noun...). Only when using the imperative form, that is when orders are given, subject it is implied and therefore could be skipped.

Now, in the sentences A-D there are some errors that appear to be unclear to expressed what was meant. First of all, they are some instructions to use an app, so the correct form to use is the imperative, in order to make the message clear.

But, only sentence B and C use this form, though they do not use a correct verb. Sentence B uses "Pull up" to express that the app should be open, which makes the verb used ambiguous. The correct verb should be "to open"; and sentence C uses the verb "to tell" when referring to accessing to a function offered by the app, and that normally has a button that has to be pressed to lead to the requested function. So the correct verb should be "to press".

On the other hand, Sentence A is not coherent because it is not in the imperative form, but in the indicative, and it is expressed as the complement of sentence B, more than a sentence of itself. And sentence D is the indicative form and in present perfect.

So, an improve construction of the sentences is the following:

A. Use the new app to record receipts quick and easy.

B. Open the app on a smartphone.

C. Push the button: "New entry".

D. Snap a photo of your receipt.
