What do mean the inlet of heat exchanger? inlet of fluid is called inlet.

@Yasin consider the following.
1. Hot fluid enters from left.
2. Cold fluid enters from the right.
(since it is counter flow HE both fluids will enter in opposite direction i.e. left and right respectively.
3. Hot fluid will become cold and leaves from the outlet.
4. Cold fluid gets hotter and leaves from left.
Now consider 1 & 4, both fluids at the inlet are hot.
1. Hot fluid enters from left.
2. Cold fluid enters from the right.
(since it is counter flow HE both fluids will enter in opposite direction i.e. left and right respectively.
3. Hot fluid will become cold and leaves from the outlet.
4. Cold fluid gets hotter and leaves from left.
Now consider 1 & 4, both fluids at the inlet are hot.

Both the hot and cold fluid has separate inlet then why we just count the inlet of the hot fluid side?

@Kedar it's an outlet for the cold we can't consider inlet for both.

No @Kedar.
Option D is the right option.

Both the fluids at inlet are in their hottest state.
