The question asks to identify the sentence(s) that correctly use the word 'devise'. Let's analyze the meaning of 'devise' and its usage in each sentence.

Understanding the Meaning of 'Devise'

'Devise' is a verb that means to plan or invent something, typically a complex procedure or mechanism, through careful thought.

Sentence A Analysis

Sentence: A. Keep this electronic devise out of reach of children.

In this sentence, the word used is 'devise', but the context suggests the intended word was 'device'.

• 'Devise' is a verb (to plan or invent).
• 'Device' is a noun, referring to an electronic gadget or piece of equipment.

Therefore, the spelling 'devise' is incorrect for the intended meaning of an electronic object. This sentence does not correctly use the word 'devise'.

Sentence B Analysis

Sentence: B. Sam devised a fundraising strategy for the welfare of the childcare foundation's orphan children.

Here, 'devised' is used as a past tense verb.

• The sentence implies that Sam planned or invented a fundraising strategy.
• This usage aligns perfectly with the meaning of 'devise' (to plan).

Thus, Sentence B correctly uses the word 'devise'.

Sentence C Analysis

Sentence: C. The terrorists devised a plan to attack the Colaba market during the festive season.

In this sentence, 'devised' is also used as a past tense verb.

• The sentence indicates that the terrorists planned an attack strategy.
• This usage matches the definition of 'devise' (to invent or plan).

Therefore, Sentence C correctly uses the word 'devise'.

Conclusion on Sentence Correctness

Based on the analysis:

• Sentence A uses the word incorrectly and likely with the wrong spelling for the context.
• Sentence B correctly uses 'devised' to mean planned a strategy.
• Sentence C correctly uses 'devised' to mean planned a plan.

The sentences that best express the meaning of the word 'devise' are B and C.
