    B) 1270 torr

    Explanation:

    Given data

    Initial volume (V₁) : 5.00 L Initial pressure (P₁) : 760 torr Final volume (V₂) : 3.00 L Final pressure (P₂) : ?

    We can find the final pressure using Boyle's law.

    P₁ * V₁ = P₂ * V₂

    P₂ = P₁ * V₁/V₂

    P₂ = 760 torr * 5.00 L/3.00 L

    P₂ = 1.27 * 10³ torr = 1270 torr

    The final pressure is 1270 torr.
