As already stated LASORs has no legal status, it is now out of date and is not likely to contain any air law questions.
JAR-FCL is not law either though bits of it have been incorporated into the ANO.
The UK ANO is something you should be familiar with, in particular Schedule 7 which relates to licences and privileges together with a number of essential articles. The ANO is incorporated into CAP393 which also includes the Rules of the Air. Since JAR-FCL was introduced the Air Law syllabus has included totally irrelevant questions on the Chicago Convention often at the expense of more important questions on Rules of the Air.
Regarding the Pink AIC number; I suggest the question is actually looking to see if you can work out from the number given, which is a Safety related AIC. e.g. AIC126/2006 (Pink 110) is clearly a Safety AIC whereas White, Green or Mauve are not.
