What Hindu female deity has four arms two of them holding roses?

Answer 1

First thing, Hindu deities do not hold roses in their hands, they hold a lotus. Two roses or lotuses would be a little too much as there could be other things that the deity could hold. So, each hand would hold a different thing. The things that they hold indicate their sphere of inflence or their specialization, for example, Saraswati holding a string instrument (Veena) or a book means she is the goddess of learning.
