An unmanned satellite $A$ and a spacecraft $B$ are orbiting around the earth in the same circular orbit as shown. The spacecraft is ahead of the satellite by some time. Let us consider that some technical problem has arisen in the satellite and the astronaut from $B$ has made it correct. For this to be done, docking of two ( $A$ and $B$) is required (in layman terms connecting $A$ and $B$). To achieve this, the rockets of $A$ have been fired in forward direction and docking takes place as shown in the figure below:

Take mass of the earth $=5.98\times {10}^{24} \mathrm{k}\mathrm{g}$
Radius of the earth $=6400 \mathrm{k}\mathrm{m}$
Orbital radius $=9600 \mathrm{k}\mathrm{m}$
Mass of satellite $A=320 \mathrm{k}\mathrm{g}$
Mass of spacecraft $=3200 \mathrm{k}\mathrm{g}$
Assume that initially spacecraft $B$ leads satellite $A$ by $100 \mathrm{s}$, i.e., $A$ arrives at any particular position after $100 \mathrm{s}$ of $B\text{'}\mathrm{s}$ arrival. Based on the above information answer the following question.

To dock $A$ and $B$ in the above-described situation, one can use the rocket system of either one, i.e., either of $A$ or of $B$. To accomplish docking in the minimum possible time, which of the following is the best way?
