What is the correct storage size for the Decimal (System.Decimal) data type in C#.NET? Select the best answer in bytes.

Introduction / Context:
Decimal is the preferred numeric type for financial calculations due to its base-10 precision. This question asks for its exact size in memory.

Given Data / Assumptions:

• We are concerned with the fixed size of System.Decimal as defined by the CLR.

Concept / Approach:
System.Decimal is a 128-bit type, which equals 16 bytes. It stores a 96-bit integer plus a scaling factor (number of decimal digits) and a sign, enabling precise decimal arithmetic without many of the rounding artifacts found in binary floating-point types.

Step-by-Step Solution:

Verification / Alternative check:
Use sizeof(decimal) (unsafe) or consult official documentation referencing Decimal's 128-bit layout.

Why Other Options Are Wrong:
They correspond to sizes of other primitives (Single 4 bytes, Double 8 bytes) or arbitrary distractors.

Common Pitfalls:
Confusing Decimal with Double since both represent fractional numbers; Decimal is larger and decimal-based.

Final Answer:
16 Bytes
