Which of the following ways of instruction is suitable for hearing impaired…

Instruction for children with hearing impairment in an inclusive classroom is built on several complementary communication channels rather than a single method, because the degree and nature of hearing loss varies by learner: some rely more on manual communication, others on visual-oral cues, and most benefit from more than one channel working together.

Each of the four techniques named in the question addresses a different channel of communication:

• Sign language: a full visual-manual language with its own grammar, used especially by learners who communicate primarily through the manual channel.

• Finger spelling: a manual alphabet that spells out words letter-by-letter, useful for names, technical terms, and words that have no established sign.

• Lip reading (speechreading): the learner watches the speaker's mouth and facial movements to follow spoken language visually.

• Cued speech: hand shapes placed near the mouth while speaking, used to disambiguate speech sounds that look identical on the lips (for example "p", "b" and "m"), making lip reading more reliable.

Each of these four techniques is, independently, a professionally recognized instructional method for hearing-impaired learners, even though a particular learner or lesson may draw on a different combination of them at any given time. Since the question asks which listed ways of instruction are suitable, the correct code is the one that includes all four rather than only some of them. This matches the officially released BSEH HTET 2024 (Computer Science branch) answer key, which marks the code covering all four methods as correct.

Correct code: (a), (b), (c) and (d).
