In a paper for an art history class, a student claims that Agnes Martin's 1957 painting Harbor Number 1 marks a significant change in Martin's artistic development.
Which quotation from an art history textbook would most effectively support the student's claim?
"Harbor Number 1 has been analyzed extensively since it was first exhibited, as no two viewers seem to agree about exactly what the painting means."
A
"Although Martin was clearly influenced by other artists of her time, she was also an artist ahead of her time, as Harbor Number 1 demonstrates."
B
"The paintings that Martin produced before Harbor Number 1 can be thought of as belonging to her earlier style, to which she never returned."
C
"Of all Martin's paintings, none so clearly represents her abilities and ideas as Harbor Number 1."
