Alright, so the question’s talking about a "racemose" inflorescence — that’s basically when flowers grow on the sides of a main axis, kind of like how grapes hang off a stem.  

Now, the twist here is that they’re asking about when it’s branched. In plant lingo, when that main axis doesn’t just have flowers directly on it, but instead has smaller branches that hold clusters of flowers, it takes on a specific name.  

Let’s picture it: you’ve got the main stem, then it sends out side branches, and those carry little flower clusters. This is different from something like an umbel (where all flower stalks spread from one point, like an umbrella) or a head (where flowers are just packed together in one solid cluster).  

So… think about which option in your list best matches “a racemose with branching in the axis.” I’ve got my guess, but I want you to picture the structure in your mind first — which one feels like "branching grape clusters"?  

Do you want me to walk you through each of those four options quickly so it clicks instantly?
