To control for an internalerror exception you should use a(n) connection.
a
unbuffered
b
buffered
c
secure
d
open

(B) Buffered

Explanation:

 Buffered connection is basically used to control the internal error exception. The buffer cursor are basically executed different queries like fetchall() and fetchone(), these are the row fetching method. It is basically used to return the row from set of the buffered row.

For creating the buffered cursor we can use the buffered argument and call the cursor connection.

On the other hand, all the other options are incorrect because it cannot control the internal error only buffered connection can do.

Therefore, Option (B) is correct.
