The correct option is A Journeying to
The second sentence of the passage states that on Wednesdays, when other folks are on their way to the church, Wilkinson and Coristine are on their way to a meeting of the literary society. In this context, 'wending their way' definitely means journeying to and not any of the other choices that are provided. Though there might be some confusion with B, it cannot be our answer because hastening to means 'to move or travel quickly' and both then men are not 'travelling quickly'. Therefore, A is our answer.
