During isothermal process internal energy of system always remains constant hence change in it will be zero every where during the process.

Q. If an ideal gas undergoes isothermal process from some initial state $i$ to the final state $f$ , then the change in internal energy during this process is

$d U = d Q$

$d U = - d W$

$d U = 0$

$d U - d W$

Q. If an ideal gas undergoes isothermal process from some initial state i to the final state f, then the change in internal energy during this process is

dU=dQ

dU=−dW

dU=0

dU−dW
