A Correct answer
Explanation

Iron is a metal with high thermal conductivity, meaning it transfers heat quickly through its structure. Wood is an insulator with much lower thermal conductivity, so it absorbs and transfers heat more slowly. This is why metals feel hot quickly when placed in sunlight.
