Some ribbon worm species will consume themselves (auto-cannibalism) when they cannot find food elsewhere. This extreme survival behavior allows them to sustain themselves temporarily by absorbing their own body tissues. It's a last-resort mechanism when facing starvation.

Giant pandas are highly specialized herbivores with bamboo comprising approximately 99% of their diet. They rarely eat anything else in the wild - occasionally small rodents or other vegetation, but bamboo is their primary and almost exclusive food source. They have evolved specialized adaptations to digest bamboo.

Leeches have 32 segmental ganglia (clusters of nerve cells) along their body, which are often referred to as 32 brains. Each segment has its own neural center that can function independently. This distributed nervous system allows leeches to coordinate movement and respond to stimuli across their body segments.

Dr. Vikram Sarabhai is widely regarded as the father of the Indian Space Program, making option C correct. He founded ISRO's predecessor, INCOSPAR, in 1962.

IRS (Indian Remote Sensing) is ISRO's satellite program for earth observation and resource management. These satellites provide data for agriculture, drought monitoring, and disaster management. The other options are incorrect - IRS is not related to rocket services, radiation satellites, or revenue services.

The primary purpose of IRS satellites is natural resource management - monitoring agriculture, water resources, forests, and disasters. While they can measure various environmental parameters, their core mission is resource management, not precipitation or radiation specifically. Option 'All' is too broad.

GSLV (Geosynchronous Satellite Launch Vehicle) is indeed the correct expansion. It's ISRO's launch vehicle designed to place satellites into geosynchronous transfer orbits, capable of carrying heavier payloads than PSLV to higher orbits.

PSLV (Polar Satellite Launch Vehicle) has been one of ISRO's most reliable workhorses with a high success rate. This question reflects its historical performance as one of the most successful launch vehicles globally, particularly for placing satellites into polar orbits.

The Indian National Satellite (INSAT) system is a series of multipurpose geostationary satellites used primarily for telecommunications, broadcasting, and meteorology. Improving the communication system is its core function, unlike IRS which manages natural resources.

India's space program formally began in the early 1960s with the establishment of INCOSPAR (Indian National Committee for Space Research) in 1962 and the Thumba Equatorial Rocket Launching Station in 1963. 1960s marks the foundational decade.
