hello
from the question given, we know the accumulated points is less than 56 but a multiple of 6.
to solve this questin faster, let's write down multiple of 6 up to 56
multiples of 6 are
![6,12,18,24,30,36,42,48,54\ldots](https://img.qammunity.org/2023/formulas/mathematics/college/doa5chw1qb7e8ql2v7gvrv2vdy82tpdl8o.png)
from the series above, we can deduce from the options that the score is 42 since it's the only corresponding multiple of 6 less than 56 here.
the answer to this question is option A
