Database Design Using Normalization Each answer below shows example data from a table. Which answer is an example of the inconsistent values problem? Three rows have the values Brown, NULL, and Blue in the same column. Three rows have the values Brown Small Chair, Small Chair Brown, and Small Brown Chair in the same column. Three columns have the values 534-2435, 534-7867, and 546-2356 in the same row. One row has the value "He is interested in a Silver Porsche from the years 1978-1988" in a column.
