NEET 2010 Biology question

The fruit fly Drosophila melanogaster was found to be very suitable for experimental verification of chromosomal theory of inheritance by Morgan and his colleagues because

(1)It completes life cycle in about two weeksCorrect
(2)It reproduces parthenogenetically
(3)A single mating produces two young flies
(4)Smaller female is easily recognisable from larger male
