What is common to the techniques (i) in vitro fertilisation, (ii) Cryo
preservation and (iii) tissue culture?
a. All are in situ conservation methods.
b. All are ex-situ conservation methods.
c. All require ultra-modern equipment and large space.
d. All are methods of conservation of extinct organisms
The answer is the option (b) All are ex-situ conservation methods.
Explanation: Option (a) can be easily ruled out. Tissue culture does not require large space and hence option (c) can be ruled out. Extinct organisms cannot be conserved, so option (d) can be ruled out.
