Final answer:
Bob Dylan's first big hit was "Blowin' in the Wind," released in 1963, and became an anthem for the civil rights movement, establishing him as a significant voice for social change.
Step-by-step explanation:
The first big hit for Bob Dylan was "Blowin' in the Wind," which he performed and released in 1963. This song became an anthem for the civil rights movement and helped to establish Dylan's reputation as a protest singer and influential songwriter. While "Like a Rolling Stone" is perhaps one of his most recognized songs, it came later in his career in 1965 and was not his first big hit. Additionally, "The Times They Are a-Changin'" was indeed a significant song, released in 1964, and is particularly remembered for its call to action during a time of social upheaval, aligning with the civil rights movement. "Mr. Tambourine Man", although a poetic masterpiece and famously covered by The Byrds, was also not his first big hit. The correct answer is a) "Blowin' in the Wind; Yes".
