Usually a teacher faces problem while teaching word problems. Many a times students solve the question when the teacher tells the operation to be used. What is the possible reason for such problem ?

Correct option is B

The answer is (b). Students lack comprehension skill.
Word problems often involve complex language and require students to understand the mathematical concepts being applied in order to solve them. If students lack comprehension skills, they may struggle to understand the problem itself, let alone identify the appropriate operation to use. This can lead to frustration and a reliance on the teacher to provide cues or instructions.
