The correct answer is option b) expertise Mrs. Deverell brought to her household tasks.
The use of "arts" in line 51 most directly emphasizes the expertise Mrs. Deverell brought to her household tasks.
"She felt as if she had squandered her time gaining talents that would eventually be useless to her.
Her weather-eye for a good drying day, her keen ear for evaluating the gentle singing sound of meat roasting in the oven, her touch for the freshness of meat, and her ability to detect if a cake had been cooked by smelling it were all examples of these talents.
These practices, which took a long time to develop, are no longer practiced." - From the context, it is evident that "arts" refers to Mrs. Deverell's ability with household chores.

If it is a single transformation, it will need to be a homothetic transformation.
None of the points remain at the old place, so it cannot be a scaling problem with respect to one of the existing points.
A homothetic transformation is bacically a scaling problem, with respect to an arbitrary point called the homothetic centre.
The centre, O, if it exists, is along the point joining any original point and the transformed point.
Here, take a pencil (imaginary one if you wish) and join points AA', BB', CC', DD', EE' and you will find that they are concurrent at point O (3,-6).
So O(3,-6) is the centre of homothety.
The scale factor, as usual, is AO/A'O, or BO/B'O... for transformation from X to Y (X is ABCDE), or the reciprocal if it is from Y to X.
