I have a question here:
what is the difference between two statements:
1) only one candidate had a distinction in maths and literature
2) only one candidate had a distinction 'both' in maths and literature
And what do you mean by
d had a distinction in both history

I guess you have written the problem in hurry without paying much attention to these things which are crucial. In future, if you want me to answer a problem make sure you check the question twice before posting it.

This is the right answer (Working is little long, hence omitted):
A has distinctions in Mathematics and Literature only.
B has distinctions in Mathematics, Philosophy and History only.
C has distinctions in Literature and Philosophy only.
D has distinctions in Literature and History only.

Hence, B is given the award.
