An increase in Temperature would result in an increase in volume as the metal may have expanded in one way or the other.
density decreases bcos density is inversely proportional to volume
as volume increases due to increase in Temperature, its density would reduce

the answer is c because when a metal is not heated it is strong but when heated it is flexible
