Solution

The correct option is C Polyethylene glycol and sodium nitrate
Polyethylene glycol and sodium nitrate enhances or induce fusion of protoplasts.
IAA plays a key role in both roots and shoots development.
Gibberellins are plant hormones that regulate growth and influence various developmental processes, including stem elongation, germination, dormancy, flowering, sex expression, enzyme induction, and leaf and fruit senescence.
Sodium is not an essential element for plants but can be used in small quantities, similar to micronutrients, to aid in metabolism and synthesis of chlorophyll. In some plants, it can be used as a partial replacement for potassium and aids in the opening and closing of stomates, which helps regulate internal water balance.
Kinetin induces cell division.
