The correct statements about Renaissance art are 1 and 3.
Statement 1 is correct because: Renaissance means rebirth. This period is characterized by a renewed and intensified interest in classical philosophy and classical art. Old sculptures and politics works inspired Renaissance artists and scientists.
Statement 3 is correct because: Renaissance art takes a more realistic and naturalistic view of the human being (not only children). That's why paintings and sculptures from this period use many techniques to produce this sensation of realism which are: the use of perspective through a one-linear perspective that gives profundity to the painting; these artists also studied human anatomy and this shows in their works, where the human body is presented symmetrically.
Statements 2 and 4 are incorrect because they refer to medieval art.
