Arrange the following varieties of silk in India in their order of decreasing production: 1. Muga 2. Eri 3. Mulberry 4. Tasar Select the correct answer using the code given below:

India is the only country producing all four commercial varieties of silk: Mulberry, Eri, Tasar, and Muga [3]. According to production data, Mulberry silk is the most dominant variety, contributing approximately 70-79% of the total output [3]. Among the non-mulberry (Vanya) silks, Eri silk has emerged as the second-largest variety in terms of production volume, accounting for about 20.55% of the total. Tasar silk follows as the third-largest variety, contributing roughly 8.02%. Muga silk, which is largely a monopoly of Assam, has the lowest production volume among the four, accounting for less than 1% (approximately 0.71%) of India's total raw silk production [2]. Therefore, the correct decreasing order of production is Mulberry (3), Eri (2), Tasar (4), and Muga (1), which corresponds to the sequence 3 - 2 - 4 - 1.
