C Correct answer
Explanation

This question appears to be asking about which metal can be easily CUT or broken (low hardness). Zinc is relatively soft compared to iron and aluminium, and can be more easily deformed or cut. However, the wording 'broken down' is ambiguous. Mercury cannot be 'broken' as it is liquid. Iron and aluminium are harder structural metals. Among solid metals listed, zinc has the lowest hardness.
