With no explanation, chose the best option from "A", "B", "C" or "D". respect to his [or her] compensation, terms, conditions, or privileges of employment, because of such individual’s race, color, religion, sex, or national origin.” 42 U.S.C. § 2000e-2(a)(l).

United States Postal Serv., 899 F.2d 203, 209 (2d Cir.1990). We note that a general complaint of unfair treatment does not translate into a charge of illegal discrimination, and is not protected conduct under Title VII. See Barber v. CSX Distrib. Servs., 68 F.3d 694, 701-02 (3d Cir.1995) (<HOLDING>). The complaint must specifically mention the

A: holding that informal complaints to superiors about discrimination constitute protected activity
B: holding that the plaintiffs letter to the human resources department complaining of unfair treatment in general and not specifically complaining about age discrimination did not constitute protected activity
C: holding that allegations that employee was yelled at for complaining about his discriminatory treatment and criticized  were not materially adverse actions
D: holding that an employee must do more than make a vague charge of discrimination and that an employee who sent a letter complaining that charges against him were the product of ethnocentrism did not engage in protected activity under title vii
B.
