Hazelnut,
With respect you are answering a question Haroon didn't ask. Approach climb has nothing to do with this.
To answer the question why the different figures for A) and B) with regards landing climb weight limit.
Well normally all figures from dispatch data will differ from inflight data because relevant dispatch data
includes the regulatory extra factors to the data that are required to legally dispatch whereas B) is simply what the aircraft will physically do when inflight hence the name. Remember once you have moved under your own power the dispatch figures are meaningless and the unfactored "inflight" data is all you need to legally land.
Having said all of that you might want to check your data again because with regards Landing climb weight limits for 30c with PA 0 there is no difference on my manuals. Both dispatch and inflight show 376.6 and that's also for both FAA and JAA.
