Solution

The correct option is D Assertion is incorrect but Reason is correct
Bronze is an alloy consisting primarily of $c o p p e r (90 %)$ , commonly with about $12 - 12.5 %$ $t i n$ and often with the addition of other metals (such as aluminium, manganese, nickel or zinc) and sometimes non-metals or metalloids such as arsenic, phosphorus or silicon, and It is also harder than pure iron and far more resistant to corrosion.

Thus, the assertion is incorrect but the reason is correct. Option D is correct.
