在处理日志文件时，需要把日志的行顺序反转，方便查看最新的日志记录（即文件里的内容按行倒序）。下面哪个代码能正确实现？（ ）

A： with open('old_file.txt', 'r') as f1, open('new_file.txt', 'w') as f2: lines = f1.readlines() lines.reverse() f2.write(lines)

B： with open('old_file.txt', 'r') as f1, open('new_file.txt', 'w') as f2: lines = f1.read() lines.reverse() f2.write(lines)

C： with open('old_file.txt', 'r') as f1, open('new_file.txt', 'w') as f2: lines = f1.readlines() for line in reversed(lines): f2.write(line)

D： with open('old_file.txt', 'r') as f1, open('new_file.txt', 'w') as f2: lines = f1.read() for line in reversed(lines): f2.write(line)
