Two major sources of mutation are radiation and reactive oxygen species (ROS).The reactive oxygen species hypothesis for aging postulates that 
1) Senescence results from the accumulation of DNA, lipid, and protein damage inflicted by ROS of mitochondrial origin; and
2) Mitochondria of long-lived species should produce high ROS than do mitochondria of short-lived species.
3) the capacity of mitochondria to consume ROS might distinguish long-lived species from short-lived species, rather than differences in ROS generation.

Following statements are given regarding to the genes in Drosophila.

A. The anterior posterior compartment of each segment of drosophila is regulated by the expression of engrailed and wingless genes.

B. The gap genes are activated or repressed by the maternal effect genes, and are expressed in one or two broad domains along the anterior-posterior axis.

C. The transcription patterns of the anterior gap genes are initiated by the different concentrations of the Hunchback and Bicoid proteins.

D. The segment polarity genes encode proteins that are constituents of the delta-notch and Hedgehog signaling pathways.

E. After the segmental boundaries are set, the pair-rule and gap genes interact to regulate the homeotic selector genes, which specify the characteristic structures of each segment.

Which one of following option has all the correct statements?
