A) 0.20 L

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

According to the neutralization law,

M_1V_1=M_2V_2

where,

M_1 = molarity of stock H_2SO_4 solution = 10.0 M

V_1 = volume of stock H_2SO_4 solution = ?

M_2 = molarity of dilute H_2SO_4 solution = 0.50 M

V_2 = volume of dilute H_2SO_4 solution = 4.0 L

$10.0\times V_1=0.50\times 4.0$

V_1=0.20L

Therefore, the volume of 10.0 M H_2SO_4 solution needed to prepare 4.0 L of 0.50 M H_2SO_4 is 0.20 L
