can you please let me know why the answer B is correc. iknow that min is -0.0,max is 0.0.but i'm not sure sbout the Math.min-0.0,+0.0)== Math.max(0.0,+0.0));

Negative zero compares equal to regular zero (positive zero), but the two zeros may be distinguished by division: one divided by negative zero yields negative infinity; one divided by positive zero yields positive infinity.
