Correct Answer: (e) None of the above/More than one of the above
Solution:During the Gupta period Tamralipti of Bengal was an important port which was used for trading with South-East Asia, China, Lanka, Java, Sumatra etc. Bhrigukatchha (Bharuch) was important port of western India from where trade of North India with western countries occured through sea-route. During the Gupta period, most of the Indian trade happened with South-East Asia, hence Tamralipti was most important port of this period. However, Bharuch, Kalyan, Cmbay etc. were also used for North Indian trade. Hence most suitable answer would be more than one which is option (e).
