Answer:
charge flowing in the copper wire is 
Explanation:
We have given current i = 2.35 A
Time through which charge is charge is transferred 
We have to find the charge flowing in this time
We know that charge is given by Q = i×t , here i is current and t is time
So charge = 
So charge flowing in the copper wire is

In this item, there needs to be a basis as to how many significant numbers can be present in a certain figure. If the answer 327.66 m/s is to be expressed as a 3 significant figures only, the answer would have to be 328. What was done here is to simply round up the units digit of the number since the decimal place (tenths) digit has a value of greater than 4.
The answer to this item is therefore letter B.
