Focus on correct verb–preposition usage with 'enter' and provide the grammatically improved sentence for SEO-friendly English learning.

Given data

• A: After opening the door
• B: we entered into the room
• C: next to the kitchen
• D: No error.

Concept/Approach (verb complementation)
The verb enter is transitive in standard English and does not normally take the preposition 'into' before its object. We say 'enter the room', not 'enter into the room' (unless used in the phrasal sense 'enter into an agreement').

Step-by-step correction
Replace B: 'we entered into the room' → 'we entered the room'.Corrected sentence: 'After opening the door, we entered the room next to the kitchen.'

Verification/Alternative
If motion must be highlighted, use 'went into the room'; with 'enter', omit 'into'.

Common pitfalls
Overusing 'into' after motion verbs that are already transitive (enter, approach).

Final Answer
B — 'we entered into the room' is erroneous; write 'we entered the room'.
