Statement I is correct. Gujarat was a major maritime trading hub in the medieval period, with extensive connections to Southeast Asia (Malacca, Indonesia), the Persian Gulf, and East Africa. Statement II is incorrect. Spices like cloves, nutmeg, and mace were primarily imported into India from Southeast Asia via ports like Malacca, not exported from Gujarat to those regions. Indian spices like pepper were traded, but they weren't the main export from Gujarat to Malacca/Indonesia. Statement III is correct. Lodovico de Varthema, an Italian traveller who visited India in the early 16th century, described Cambay as a massively busy port. While the figure "more than 1000 ships every day" might be an exaggeration, it reflects the immense traffic and scale of trade at Cambay that Varthema indeed reported and marvelled at.
