Answer:
 Beta = 1.18
Step-by-step explanation:
The computation of the beta is shown below:
But before that we need to calculate the following calculations
Current stock price = D1 ÷ (Required rate of return - growth rate) 
 $85 = $4.30 ÷ (Ke - 0.08) 
 (Ke - 0.08) = 0.0506 
 Ke = 0.1306 
= 13.06% 
 Now 
Expected rate of return(Ke) = Risk free rate + Beta × (Market rate of return - Risk free rate of return) 
 13.06% = 6% + Beta × (12% - 6%) 
 13.06% = 6% + Beta × 6% 
So, the Beta = 1.18
