    Hello, Average molecular weight of an amino acid is 110Daltons. So, Assuming the molecular mass given in the question is in Dalton, 200000 ÷ 110 = 1818.18181.... So, Approximately 2000 amino acids can be present in a polypeptide of 200000 Dalton weight. I hope this answers your question. Please reply back if you didn't understand anything. Thank you.

    one amino acid weight is approx 128 but when it join it loose a molecule of water so 128-18=110approx . give polypeptide mass =200000 and one amino mass approx 110 so we divide 200000/110=1800approx so and would be B option 2000
