The following sentence has been split into four segments. Identify the segment that
contains an error.
My father told me / that in his childhood / he was walking / to school every day.

Correct option is A

Option (a) contains an error.
· The error in the segment "he was walking" relates to the tense used. The sentence context suggests a habitual past action, which should be expressed as "he walked" to indicate a routine or regular activity during his childhood.
· Grammatical rule used: For habitual actions in the past, simple past tense is typically used instead of past continuous, which is generally reserved for actions that were ongoing at a specific time. Using "he walked" instead of "he was walking" aligns with this rule.
