Explanation by: Mr. Dubey

The valid range of long double depends on the system and compiler, but typically for most modern compilers (like GCC with x86-64 architecture using 80-bit extended precision), the range is:

Correct Answer:

✅ (A) 3.4E-4932 to 1.1E+4932

Explanation:

long double in most modern systems uses 80-bit extended precision (sometimes 128-bit on specific architectures).
Its range is significantly larger than double, which has a range of approximately 1.7E-308 to 1.7E+308.
The values 3.4E-4932 to 1.1E+4932 match the standard long double range on many x86-64 systems.

Would you like to confirm the range for a specific compiler (like GCC, Clang, or MSVC)?
