Step 1: Read the question.
We must find which city will host the 2026 Commonwealth Games.
Step 2: Recall the original host.
The 2026 Games were first awarded to Victoria, Australia.
Step 3: Note the withdrawal.
Victoria pulled out in 2023 over rising costs, leaving the event without a host.
Step 4: Recall the replacement.
The Commonwealth Games Federation chose Glasgow, Scotland, as the new host.
Step 5: Recall why Glasgow.
Glasgow already had venues from the 2014 Games, lowering cost and risk.
Step 6: State the answer.
The 2026 host is Glasgow, option B.
\[ \boxed{\text{Glasgow}} \]
