Correct answer: C
CONCEPT: A Learning-Teaching Resource (LTR) is best suited to a visually challenged learner in mathematics when its ordinary classroom use routes the mathematics through touch or hearing directly — the learner can feel a physical representation of the numbers or hear the content read aloud — rather than needing a printed or on-screen visual layout to be independently interpreted first. When a QUESTION asks for a SET of such resources, every member of that set must independently meet this bar; one non-qualifying member is enough to rule the whole set out, regardless of the other member.
APPLICATION: Taylor's abacus represents numbers physically in the arrangement of its pegs and moveable pins/discs, so a visually challenged student forms numerals and carries out arithmetic operations directly by touch, with no separate configuration step. A computer running screen-reader and text-to-speech accessibility software — a standard classroom accessibility setup — converts mathematical content, instructions, and problems into speech the same student hears directly. Both therefore route mathematics through a built-in touch-or-hearing pathway.
CROSS-CHECK — why the other two tools are not the exam's intended choice here:
GeoGebra's ordinary classroom use is reading a plotted graph or dynamic geometric figure directly off the screen: the mathematics is conveyed by the shape of the figure, which a visually challenged learner needs re-described or reconstructed rather than perceiving directly.
A spreadsheet's ordinary classroom use is reading values by their position in a grid of rows and columns: the mathematics is conveyed by that positional layout, which again needs re-describing cell by cell rather than being perceived directly.
Result: Taylor's abacus (direct tactile representation) and a computer set up with screen-reader/text-to-speech software (direct auditory access) are the exam's most appropriate LTRs for a visually challenged student in this mathematics classroom — Taylor's abacus and Computer.
