How to position features on landing page [on hold]

I'm working on a landing page of a new product iteration, on which I want to list the new features for existing users. But I'm thinking about the reading pattern to use on this landing page and looking around, there's a lot of variety in landing pages & features pages.

What are your thoughts on reading patterns on landing pages? What do you prefer in which situation? All input is welcome!

For example the following three options:

A - without hierarchy

B - Alternating pattern

C - Left-aligned, hierarchy
