Here points mean define or represent not direction so;
Bar points(represent) - N type(-) lower potential or cathode.
Arrow points (represent)-P type(+) higher potential or anode.
And current always flows from (+)or higher potential to (-) or lower potential i.e Anode to cathode.

"The arrow in the schematic symbol of a diode POINTS TO".
This statement asks where the arrow POINTS TO, not what it represents and obviously, it points to the bar which represents the cathode.
The answer must be B.
I think it will be C if "points to" becomes "represents to".

Actually bar in the diagram represent n type and arrow pointing to bar represent p type, we know that current flows opposite to electrons. Normally anode represent -ve and cathode represent +ve i.e. arrow will points to anode. Answer c is right.

--- >|---- (fig - schematic of the diode)
In the schematic of the diode the arrow points towards the n type material which is cathode. refer the fig
So the answer should be B

The question is where the arrow points to? Arrow indicates the flow of current. So its direction is from p to n. So the arrow should point to N. Answer B is the right one.

No, diode has conventional current flow (positive to negative). But as per the symbol, cathode has -Ve anode has +Very. Listen the quest carefully.

The electrons move flow from the anode to the cathode, so naturally, current will be from CATHODE to ANODE, the same direction shown by the arrow.

According to basic symbolic representation of diode the arrow show the direction from anode to cathode & from N to P side.

Anode always positive.
The cathode is negative so p type conductor is anode because it flows +ive to -ive.
The cathode is negative so p type conductor is anode because it flows +ive to -ive.

Arrow head points to p junction means anode and bar on the other hand represents the n side means cathode.
