Step 1: Understand the question.
We must name the winner of the Nobel Peace Prize in 2025. This is a current-affairs question about a famous world award.
Step 2: Recall what the prize honours.
The Nobel Peace Prize is given for work in peace, democracy, and human rights. It is awarded by the Norwegian Nobel Committee.
Step 3: Look at the options.
Narges Mohammadi was an earlier winner from Iran. Two options spell the Belarusian name Tsikhanouskaya in two different ways, which is a hint that neither is the clean answer here.
Step 4: Identify the 2025 laureate.
The 2025 Nobel Peace Prize went to Maria Corina Machado, a democracy leader from Venezuela.
Step 5: Confirm by elimination.
Since Narges Mohammadi won in an earlier year and the two Tsikhanouskaya spellings are distractors, only Maria Corina Machado fits 2025.
Step 6: Match with the options.
The second option is correct.
\[ \boxed{\text{Maria Corina Machado}} \]
