Consider a memory system with memory allocated as shown below.

Suppose the following actions occur in order:

$$ Process E starts and requests $300$ memory units.

$$ Process B exits.

$$ Process F starts and requests $800$ memory units.

$$ Process C exits.

$$ Process G starts and requests $900$ memory units.

Which of the following will be the correct scenario for process G$?$

The Diagram:

$400--------------$

$800----------------$

B

$1600----------------$

$1900----------------$

C

$2400----------------$

$3100-----------------$

D

$3400-----------------$

Which of the following is true $?$

a$.$

Using best$-$fit dynamic contiguous allocation, the starting address of process G is $1600$

b$.$

Using best$-$fit dynamic contiguous allocation, the starting address of process G is $2400$

c$.$

Using best$-$fit dynamic contiguous allocation, the starting address of process G is $1200$

d$.$

Using best$-$fit dynamic contiguous allocation, the starting address of process G is $1900$
