Match List I with List II:

List I (Fruit crop)	List II (Commercial propagation method)
a. Mango	I. Air layering & budding
b. Grapes	II. Side grafting
c. Papaya	III. Seeds
d. Guava	IV. Hardwood cutting

Choose the correct answer from the options given below:

Correct option is D

Mango → II. Side grafting: Mango is commonly propagated commercially through side grafting, which ensures true-to-type plants with better fruit yield and quality. Grafting allows for the use of desirable rootstocks and scions.
Grapes → IV. Hardwood cutting: Grapes are best propagated using hardwood cuttings, taken during dormancy. This method is highly effective as grapes root easily from cuttings, and it's commonly used in commercial vineyards.
Papaya → III. Seeds: Papaya is usually propagated by seeds, especially for commercial production. Though seed propagation may lead to variation, it is still widely used due to its ease and cost-effectiveness.
Guava → I. Air layering & budding: Guava propagation is commonly done via air layering and budding, which helps in producing uniform and early-bearing plants. These methods are preferred over seed propagation, which leads to variability.
