US visa previous refusal


I was refused usa tourist visa back in 2011.

In the previous visa refusal section, I mentioned I was denied visitor visa ( B1/B2 ) to USA on 3 Jun 2011.
I was refused under section 214b

I realized there is sub category I applied for, and I checked and It’s visa class B2, visa category Business / Tourism.

Even though a person applies for different visa classes, these visa’s are usually issued combined as ( B1/B2 ).

Should I make this point clear to CIC or it’s ok.
