Δ U = Q + w Internal energy is a state function but Q and w are path functions.

Q. Assertion : Addition of Q and w gives $Δ U$ .
Reason : Addition of two path functions cannot give state function.

If both assertion and reason are true and reason is the correct explanation of assertion

If both assertion and reason are true but reason is not the correct explanation of assertion

If assertion is true but reason is false

If both assertion and reason are false

$Δ$ U = Q + w
Internal energy is a state function but Q and w are path functions.
