A moving coil galvanometer is converted into an ammeter, reading upto $$0.04 \mathrm{~A}$$ by connecting a shunt of resistance '$$3 \mathrm{r}$$' across it and then into an ammeter reading upto $$0.8 \mathrm{~A}$$, when a shunt of resistance '$$r$$' is connected across it. What is the maximum current which can be sent through this galvanometer if no shunt is used?

A
$$0.02 \mathrm{~A}$$
B
$$0.04 \mathrm{~A}$$
C
$$0.08 \mathrm{~A}$$
D
$$0.01 \mathrm{~A}$$
