$"1.24 m"^3$ and isochoric

$"(i)"$

At $"A"$
$"P"_1 = "6.2 atm"$
$"V"_1 = "0.6 m"^3$

At $"B"$
$"P"_2 = "3.0 atm"$
$"V"_2 = ?$

At constant temperature

$"PV = constant"$

$"P"_1"V"_1 = "P"_2 "V"_2$

$"V"_2 = ("P"_1"V"_1)/"P"_2 = (6.2 cancel"atm" × "0.6 m"^3)/(3.0 cancel"atm") = "1.24 m"^3$

$—————$

$"(ii)"$

Path $"BC"$ represents a change in pressure from $"3.0 atm"$ to $"4.2 atm"$ at constant volume. Therefore it is an isochoric process.
