Answer puts "in collecting." Whole sentence is " Is this the book in collecting the question was taken?" An affirmaative sentence is "This is the book in collecting the question was taken. " This meaning is this book is collected the question which pepole was examined by.
I don't think that can be the answer to the question. 'From which' makes perfect sense, but 'in collecting' is not 'a preposition + a pronoun', and makes no sense.
