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