The analysis component of precision agriculture which provides data storage, retrieval and transformation to spatial data is:

Correct option is A

Geographic Information System (GIS) is the core analytical tool in precision agriculture that handles spatial data.
It allows for data storage, retrieval, and conversion of various forms of information into spatial (map-based) data.
GIS enables farmers to analyze field variability and make site-specific decisions on irrigation, fertilization, and crop management.
Explanation:
(a) GIS (Global Information System) – Correct answer. Specializes in mapping, storing, and analyzing spatial data used in agriculture.
(b) GPS (Global Positioning System) – Provides location data, but does not handle spatial data analysis.
(c) DSS (Decision Support System) – Helps in decision-making using data models but is not specifically designed for spatial data transformation.
(d) VRT (Variable Rate Technology) – Uses data from GIS and GPS to apply inputs variably, not responsible for data analysis or storage.
