以下代码展示了两种实例方法复用的常见场景，请结合代码判断选项：

class BaseService:
    def log(self, msg):
        print(f'[LOG] {msg}')

    def process_data(self, data):
        self.log(f'Processing data: {data}')
        return data.upper()

class DataHandler(BaseService):
    def handle(self, raw_data):
        # 尝试复用父类的实例方法
        pass
