Which of the following teaching-learning resources can be used for helping visually- challenged students in a mathematics classroom ?
(A) Taylor's abacus
(B) Computer
(C) Geogebra
Choose the correct option

Correct option is A

Taylor's abacus and computers are both teaching-learning resources that can be used for helping visually-challenged students in a mathematics classroom.
Taylor's abacus is a tactile tool that can be used to teach basic arithmetic concepts, such as addition, subtraction, multiplication, and division. The beads on the abacus can be moved to represent numbers, and the student can then perform the arithmetic operations by moving the beads accordingly.
Computers can be used to provide access to a variety of educational software and resources that can be used to teach mathematics to visually-challenged students. This software can include screen readers, speech synthesizers, and braille output devices.
Geogebra is a dynamic mathematics software that can be used to create and manipulate geometric constructions. While it can be a valuable tool for teaching mathematics, it is not specifically designed for visually-challenged students.
