The correct option is A Only statement 1 is correct
The flower which has all the four whorls i.e., calyx, corolla, androecium and gynoecium is called the complete flower.
Whereas the flower with one or more whorls missing is called an incomplete flower.
Cucumber and maize have flowers in which reproductive whorls i.e., androecium and gynoecium are present on separate flowers.
Hence flowers of cucumber and maize plants can not be considered as complete flowers.
