阅读下列短文，从短文后每题所给的A、B、C和D四个选项中，选出最佳选项。

Wangari Maathai, a Nobel Peace Prize winner, was born on April 1, 1940, in Kenya（肯尼亚）. Growing up in the countryside, Wangari was deeply connected to the land from an early age. This early experience with the environment later inspired her life’s work, which has left an unforgettable mark on the world.

With the help of a program, Wangari received her university education in the United States. After graduation, she returned to Kenya. In 1971, she got a doctor’s degree from the University of Nairobi, becoming the first woman doctor in East and Central Africa. But her greater achievement was outside the university. In 1977, Wangari set up the Green Belt Movement, an organization focused on tree planting, environmental protection, and women’s rights. She called on Kenyan women to plant trees in their hometown. This simple act not only helped to protect the environment but also made women powerful economically（经济地）and socially.

Wangari focused not only on environmental problems. She made great efforts to fight for democracy（民主）, human rights, and social fairness. Her activism（激进主义）often put her in disagreement with the Kenyan government. As a result, she was put in prison（监狱）several times, but she kept fighting bravely. It was because of her tireless work that she was awarded the Nobel Peace Prize in 2004. She became the first African woman to receive the award.

Wangari passed away on September 25, 2011, but her spirit continues to inspire a worldwide movement towards environmental protection and social fairness. Her book, Unbowed, records her life journey and the challenges she faced, offering an inspiration to countless people worldwide. Her story lives on through the millions of trees planted by the Green Belt Movement and the countless lives she touched through her hard work. It serves as a reminder that even the smallest actions, like planting a tree, can have a great influence on the world.
