Answer:
Option B. 1,100 Earth diameters
Solution:
Angular position of steroid,
(given)
To calculate the distance of asteroid, we use parallax method given as:
(1)
where,
From the relation:
l = 
we get:
distance(d) or R = 
distance(d) or R = 
d = 
distance, d = 
Comparing it with Earth's diameter:
d = 
Since, the value is close to 1,100 Earth diameters, therefore, option B is the right answer.
