Assertion:Direction of electronic current cannot be from negative potential to positive potential . 
Reason: Direction of current is in the direction of flow of electrons. 

 

A)BOTH A AND R ARE TRUE, AND R EXPLAINS A
B)BOTH A AND R ARE TRUE,BUT R DOES NOT EXPLAIN A
C)A IS TRUE ,BUT R IS FALSE
D)BOTH A AND R ARE FALSE
Please give a simple explanation too..

Dear student,
Electrons being a negative charge flows from low (negative) potential to high (positive) potential.
and we know, current flows in the opposite direction of that of electrons.
so current flows from high (positive) potential to low (negative) potential.

hence both the assertion and the reason is true and the reason properly explained the assertion.
(option A)
