A) ​ $\begin{array} { l } \cos x = \frac { 1 } { 4 } \\\\\sin x = - \frac { \sqrt { 15 } } { 4 } \\\\\tan x = \sqrt { 15 }\end{array}$ ​
B) ​ $\begin{array} { l } \cos x = \frac { 1 } { 4 } \\\\\sin x = \frac { \sqrt { 15 } } { 4 } \\\\\tan x = \sqrt { 15 }\end{array}$ ​
C) ​ $\begin{array} { l } \cos x = \frac { 1 } { 4 } \\\sin x = - \frac { \sqrt { 15 } } { 4 } \\\tan x = - \sqrt { 15 }\end{array}$ ​
D) ​ $\begin{array} { l } \cos x = - \frac { 1 } { 4 } \\\\\sin x = \frac { \sqrt { 15 } } { 4 } \\\\\tan x = \sqrt { 15 }\end{array}$ ​
E) ​ $\begin{array} { l } \cos x = - \frac { 1 } { 4 } \\\sin x = - \frac { \sqrt { 15 } } { 4 } \\\tan x = - \sqrt { 15 }\end{array}$
