Answer is option A i.e. "I and II"
Bryophyllum and Kalanchoe can reproduce by the formation of buds on leaves, i.e. they can propagate vegetatively. Mango and guava asexually reproduce or propagated through grafting. Grafting is the basic propagation option for mango and guava.
Whereas, clones have same genetic make-up but not phenotypic (e.g. their height may differ).
Vegetative propagation of sweet potato occurs through adventitious buds.
Oestrus cycle is the period in the sexual cycle of female mammals, except the higher primates.

• The potato is a starchy, tuberous crop which is native to America. Potato do not reproduce by sexual reproduction which requires seeds. 
• Potatoes are mainly propagated by vegetative methods (cloning). Potato tubers have nodes or eyes from which the new growth begins. The new stems growing from each eye are called sprouts which give rise to the new plant.
  
• So, the correct answer is 'Potatoes'.

Bryophyllum produces plantlets along the margins of its leaves. When they mature, they drop off and root in any suitable soil beneath thereby performing the function of vegetative propagation.
Thus, the correct answer is option (A), 'Leaf'.

When the buds arises on the leaves they are called as epiphyllous buds, e.g., Bryophyllum. Epiphyllous budding is a unique mode of vegetative proliferation in restricted plant species. Leaf detachment induces activation of these buds which then develop into plantlets by differentiating roots and shoot. Leaf detachment not only induces bud differentiation but also concurrently triggers foliar senescence. Inflorescences and vegetative shoots arise from epiphyllous buds on the adaxial surface of the rachis between the pinna pairs.  

Bryophyllum produces plantlets along the margins of its leaves. When they mature, they drop off and root in any suitable soil beneath.
Thus, the correct answer is option (C), 'Leaf'.
