The first law of thermodynamics for isothermal process is

A) q=-W

$\triangle U= W$

$\triangle U= q_{v}$

$\triangle U= -q_{v}$

Option A

According to firsr law of thermodynamics

$\triangle U= q+w$

where, $\triangle U$ = internal energy

q= Heat, w= work done

For isothermal process, $\triangle T$ =0 , $\triangle U$ =0

q=-w
