I think you should admit your mistake now and move on. A block can refer to any large trade in any instrument. When someone says that a 100,000 block traded in an SLV option, it means that there was a trade for 100,000 contracts or, alternatively, you could say 100,000-contract block trade. You can find the definition from CME here.

Block trade refers to size. Some define it as shares and bonds. Others include futures and options. Does it really matter?
