Hey Swati,
Unfortunately right now, CC and BCC aren't possible to use in an outgoing Marketo email. A possible workaround would be to set your VP of Sales' email address as the "reply-to" address, that way if someone expresses interest via email, the default person they'll send an email to is your VP of sales. If that's an issue for visibility to the rest of the sales team, consider setting the reply-to address as a distribution list that all the necessary people are included on.
If you want to see CC/BCC functionality in Marketo, there already exists an idea in the community that you can vote on:

Hope this helps!
