Answer: Option 4

When a gas is subjected to adiabatic expansion like throttling any real fluid will lose some of its internal energy (mainly pressure energy if the flow is assumed to reach fully developed flow n a horizontal pipe without any inclination) to do work against non-conservative force friction and the fluid temperature should rise but according to ideal gas law if the pressure decreases than temperature also should decrease so, it depends on which effect is dominating.
