User comments below. All of them might not be correct.

Ans is b.here Min_Exponent is an static final variable which tells the min power an float variable can have..here it will return the -126

Ans is Option A.... after execution starts it will go to println statement we have given float.min_exponent that means in predefined class Float having static and final variable MIN_EXPONENT initialized with the value of -126 so it will print the value of MIN_EXPONENT as -126

i'll go with option A ... Float.MIN_EXPONENT  denotes accessing of a Static final Constant value "MIN_EXPONENT" from the class called "Float"  ... sysout prints that value and that value is Predefined in the API and is equal to -126..

Ans is A ....MIN_EXPONENT  returns the maximum negative integral exponent that the floating-point type can represent as a finite value when a base of radix is raised to that power.  so when the compiler enter into main it prints the value of float.MIN_EXPONENT as-126

ANS IS A (-126)

--Here Float class of java is used.

--In above example min_Exponent variable of "Float" wrapper class is used.Some predefined variable of class "Float" is used to display the value.

Syntax:

public static final int MIN_EXPONENT

Description:
Minimum exponent a normalized float variable may have. It is equal to the value returned by Math.getExponent(Float.MIN_NORMAL).
--Floating point variable can have exponent from "-126 to 127"

ans a ..The single-precision binary floating-point exponent is encoded using an offset-binary representation, with the zero offset being 127; also known as exponent bias in the IEEE 754 standard.
MIN_EXPONENT=01H?7FH = ?126

this value is equal to the value returned by Math.getExponent

static float MIN_NORMAL -- This is a constant holding the smallest positive normal value of type float, 2^-126.
