Singh sent his reply to the ministry last evening, within the 15-day deadline set for the same, highly-placed HRD ministry sources said.
However, both the ministry as well as Delhi University remained tight-lipped over the arguments put forth by the VC in his reply.
The reply, which sources said runs into over 100-pages, is currently being examined by the ministry and it will send its recommendations to the Visitor to DU, President Pranab Mukherjee.
Apart from inquiring as to the legality of introducing the Four-Year Undergraduate Programme (FYUP), the ministry had sought Singh's reply on the opening of B.Tech courses under the varsity without due clearance from AICTE and the diversion of funds to the tune of Rs 172 crore meant for OBC students to buy laptops.
Singh was issued a show-cause notice on March 17 after the Visitor's nod.
The FYUP was scrapped in June last year after the NDA government came to office and following pressure from UGC that it be done away with.
