In an irreversible process taking place at constant $\mathrm{T}$ and $\mathrm{P}$ and in which only pressure-volume work is being done, the change in Gibbs free energy (dG) and change in entropy (dS), satisfy the criteria

• Correct answer
  A

  $(\mathrm{dS})_{\mathrm{V}, \mathrm{E}}>0,(\mathrm{dG})_{\mathrm{T}, \mathrm{P}} < 0$
• B

  $(\mathrm{dS})_{\mathrm{V}: \mathrm{E}}=0,(\mathrm{dG})_{\mathrm{TPP}}=0$
• C

  $(\mathrm{dS})_{\mathrm{V}, \mathrm{E}}=0,(\mathrm{dG})_{\mathrm{T}, \mathrm{P}}>0$
• D

  $(\mathrm{dS})_{\mathrm{V}, \mathrm{E}} < 0,(\mathrm{dG})_{\mathrm{T}, \mathrm{P}} < 0$

Hence, the correct answer is option: 'A'.
