Direct admission into ca

Sir,
I am 23 year old, and have passed my M.Com from an Open University (University of Nagaland) with 61 % marks, but have studied only one (Accountancy) out of three relevant subjects into which a candidate should have secured 55% marks.

I am very much confused regarding Direct Admission into C.A (IPC) Course.

My queries are

a)  As per per ICAI required whether I am Commerce graduate ?

b)  If yes, then I am not eligible  ?

c)   if NO, then I am eligible for Direct admission ? (Because in M.Com I have secured 61 % marks) ?

Please reply I am very much confused regarding my eligibility.
