In a closed insulated container a liquid is stirred with a paddle to increase the temperature. Correct  conditions  are

• A

  $\mathrm{W}=0,\mathrm{\Delta E}=\mathrm{q}\ne 0$

• B

  $\mathrm{\Delta E}=\mathrm{W}=\mathrm{q}\ne 0$

• C

  $\mathrm{\Delta E}=0,\mathrm{w}=\mathrm{q}\ne 0$

• D

  $\mathrm{\Delta E}=\mathrm{w}\ne 0,\mathrm{q}=0$
