The major product of the following reactions

• A

  $\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CHBrCO}_2 \mathrm{H}$
• B

  $\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CH}_2 \mathrm{CH}_2 \mathrm{CHBrCO}_2 \mathrm{H}$
• Correct answer
  C

  $\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CH}_2 \mathrm{CHBrCO}_2 \mathrm{H}$
• D

  $\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CH}_2 \mathrm{CHBrCOBr}$

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