Seed germination requires:
$I$. Light
$II$. Suitable temperature
$III$. Moisture
$IV$. Oxygen
Select the correct option.

Study the following statements.
$I.$ "$X$" hormone promotes root growth and root hair formation, thus helping the plants to increase their absorption surface.
$II.$ "$Y$" hormone induces flowering in mango and also promotes rapid internode/petiole elongation in deep-water plants, hence helping leaves or upper parts of the shoot remain above water.
$III.$ "$Z$" hormone inhibits seed germination, increases the tolerance of plants to various stresses, and plays an important role in seed development, maturation, and dormancy.
Identify the correct names of hormones marked as $X$, $Y$, and $Z$.

An apparatus commonly used to demonstrate phototropism is

Match column-$I$ with column-$II$ and select the correct option using the codes given below.

Column-$I$	Column-$II$
$A$. Cytokinin	$i$. Stimulates closure of stomata
$B$. Ethylene	$ii$. Increases stem length
$C$. Gibberellin	$iii$. Promotes lateral shoot growth
$D$. Abscisic acid	$iv$. Found in large amounts in tissues undergoing senescence
