B. I will make an attempt and I will be convincing.
C. I try to do my best to "pull it off".
D. I "pull it off" effortlessly.
Despite the fact that the request makes perfect business sense but I happen to not believe in the particular notion that I am to advocate, I will do my best to pull it off and push the particular viewpoint with a client.
As an employee in the organization, I have to make sure that my role aligns with the organizational goals and objectives and that everything that I do goes along with what the organization wants. Even though our beliefs are different regarding the issue, what my company wants is of utmost importance than my own notion.
Therefore, I will try to do my best to "pull it off".
