A good delivery for a trade typically requires that the total number of shares matches exactly what is being traded. In this case, the trade is for 475 shares.

One of the key criteria for "good delivery" is that the share certificates can accurately represent the number of shares being traded without any fractional shares or discrepancies in the total.

In the correct option identified, which is not a good delivery, five 80-share certificates and one 75-share certificate total 475 shares; however, this distribution is inefficient because it involves several certificates that do not typically follow the standard practice. Each of the 80-share certificates being too close to the number of shares required creates complications during the delivery process, especially since delivering a larger number of smaller certificates is less practical than delivering fewer larger ones.

In contrast, the other combinations of certificates represent clearer collections of shares that can easily sum to 475, making them considered good deliveries.
