Which of the following data types is a numeric type?

The selected answer is a numeric type because it represents integers in ABAP. The 'I' data type is specifically used for storing whole numbers or integers and can cover a range of values depending on the system’s architecture—typically 4 bytes in size, allowing for storage of numbers ranging from -2,147,483,648 to 2,147,483,647.

The other choices represent different data types:

• The 'N' data type is used for numeric text fields, which can contain numbers but are treated as character strings rather than integers.

• The 'P' data type stands for packed numbers, which can store decimal values and are suitable for carrying out arithmetic operations while maintaining precision.

• 'DECFLOAT16' represents a decimal floating-point type that can also store numeric values, particularly useful for calculations requiring high precision.

While these other data types are related to numeric values, they either do not represent whole numbers directly or pertain to more specific numeric formats rather than being plain integers. Thus, 'I' is the most straightforwardly recognized numeric type among the options provided.
