Reading 24, EOC question 17, rebalancing

In the reading it states under 4. Creating Fundamental Act strategis, that the manager would need to keep ‘regular portfolio balancing’ that ensure that the investment mandat and the desired risk exposure are maintained… however in Q17, it is asked for managing a fund that is following a fundamental active investment process how to rebalance the portfolio? In my opinion it should be answer a) regular rebalancing, (as per the text of the curriculum), but it appears to be 'in response to changes in company specific information… I just wonder did I misread the Curriculum or is the answer to the question wrong?
