Section A always has to be spoken about in the context of rehearsal techniques, even if the question does not specifically mention it. I'm studying Woyzeck for Section A&B so while I can't give you any specific examples the same principles would apply to the way I write my answers (I normally get between 16 - 20 in Section A).
I always follow the Point, Example, Explain format for Section A; so the
point is your rehearsal technique, the
example is then how it is carried out/what the 'cast' do and then the
explain is HOW this links to the question. So for example, if the question was on a relationship it would follow this style...
'The relationship between Character A and B could be explored though a 'Genre Swap' rehearsal activity; this would be done through putting the cast into pairs where they would rehearse the Scene [specifically link to your scene/scenes here] in a number of different genres such as melodrama, naturalism and in a soap opera style. This would specifically explore the character's relationship as it would offer a number of interpretations by the cast, for example in melodrama the humorous exaggeration suggests a comfortable relationship while naturalism could suggest a more serious one.'
Obviously this is a bit more detailed than I would normally write as I'm typing and not doing it hand-written but it's all there! For question C though an extra sentence needs to be added which links to your final interpretation,
however DO NOT MAKE THAT YOUR FOCUS OF QUESTION C IT STILL NEEDS TO BE REHEARSAL BASED. In the example I gave linking it to a final performance idea needs only to be as simple as 'This would link to my final performance as I want the relationship between Character A and Character B to be very humorous; the melodrama developed in rehearsal emphasising this side of the relationship.'
Also! If at any point you can give a rehearsal technique which would link to a specific practitioner do so! I hope this helps with your Section A and good luck for your exam
