Find the current I.

Correct option is D

Applying Nodal analysis to node V₁-

$$-2 + \frac{V_1}{3} + \frac{V_1 - 10}{2} = 0\\\frac{V_1}{3} + \frac{V_1 - 10}{2} = 2\\2V_1 + 3V_1 - 30 = 12\\V_1 = \frac{42}{5}\\I = \frac{V_1 - 10}{2} = \frac{\frac{42}{5} - 10}{2}\\I = \frac{42 - 50}{10}\\I = -\frac{8}{10}\\I = -0.8 \text{ A}$$​
