$\mathrm{M}, \mathrm{N}, 0$ and P represent

• Correct answer
  A

  M - Germination; N - Vegetative growth of haploid cells; 0 - Vegetative growth of diploid cells; P - Starvation
• B

  M - Vegetative growth of haploid cells; N - Starvation; 0 - Germination; P - Vegetative growth of diploid cells
• C

  M - Germination; N - Vegetative growth of diploid cells; 0 - Vegetative growth of haploid cells; P - Starvation
• D

  M - Vegetative growth of diploid cells; N - Starvation; 0 - Germination; P - Vegetative growth of haploid cells

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