The correct answer is Pie Chart.

Step 1: Understand the question. The question is asking which type of chart is used to visualize the Frequency Distribution Table (FDT) when the variable being used is nominal.

Step 2: Know what a nominal variable is. A nominal variable is a type of variable that is used to name, label or categorize particular attributes that are being measured. It does not have any quantitative value and cannot be ordered in any meaningful way.

Step 3: Know the different types of charts. A pie chart is a type of chart that displays data in a circular graph. The pieces of the graph are proportional to the quantity it represents. A line chart is a way of displaying data along a number line. A histogram chart is a graphical representation that organizes a group of data points into a specified range.

Step 4: Choose the correct chart. In this case, the pie chart is the correct answer because it is best used to represent nominal data. It can easily show the proportion of each category in a clear and straightforward manner.
