Which of the following was NOT a notable estimator of India's national and per capita income during the colonial period?

Alexander Cunningham

During the colonial period, the colonial government did not make any genuine effort to accurately determine India's national and per capita income. Various individual attempts were made to estimate these incomes, but they often produced conflicting and inconsistent results. Notable individuals who made such estimations include Dadabhai Naoroji, William Digby, Findlay Shirras, V.K.R.V. Rao, and R.C. Desai. Among them, V.K.R.V. Rao's estimates were particularly regarded as significant during the colonial era.
