Solution
The correct option is B less than brass
On heating a bimetallic strip made from brass and iron, both the strips will expand. But, the brass strip will expand more than the iron strip because the linear coefficient of thermal expansion for brass is greater than linear coefficient of thermal expansion for iron.
