Step 1: Understanding the Question:
The question asks specifically for the Nobel Prize in Literature winner of the year 2011, among four names drawn from different Nobel fields and years.
Step 2: Key Fact or Approach:
Sorting each name by its actual Nobel category and year, rather than just recognising the names as Nobel laureates, is what separates the correct choice from the distractors here.
Step 3: Detailed Explanation:
Tomas Transtromer, a Swedish poet, received the Nobel Prize in Literature in 2011 for his body of poetic work marked by vivid, compressed imagery.
Mo Yan, a Chinese author, is also a Literature laureate, but his award came a year later, in 2012.
David J. Wineland worked in physics and won the Nobel Prize in Physics in 2012 for trapping and measuring individual quantum particles.
Shinya Yamanaka is a stem cell researcher who won the Nobel Prize in Physiology or Medicine in 2012.
Of the four, only Transtromer's prize matches both the Literature category and the year 2011 that the question specifies.
Step 4: Final Answer:
Tomas Transtromer is the correct winner of the 2011 Nobel Prize in Literature, so option (c) is correct.
