Final answer:
The correct moment of inertia for the Big Ben clock tower cannot be calculated without additional information such as the mass and how that mass is distributed relative to the axis of rotation.
Step-by-step explanation:
The student is asking about the moment of inertia of a large clock, specifically the clock known as Big Ben, which is a local landmark in London. Although the question mentions the clock at the Parliament tower, the provided information is insufficient to calculate the moment of inertia as key parameters like mass and distribution are not given. Moment of inertia depends on the mass distribution of the object relative to the axis of rotation, and without detailed geometric and mass data, the correct answer cannot be determined from the options provided (a 7.29 kg·m², b 5.94 kg·m², c 9.81 kg·m², d 3.62 kg·m²).
