What is the maximum number of primary partitions supported by MBR?

Explanation:
MBR keeps a partition table with four entries, and each entry can describe one primary partition. Because there are only four table entries, you can have at most four primary partitions. If you need more partitions, you use one of those primaries as an extended partition, which then contains many logical partitions inside it. So the total number of primary partitions is limited to four, though the overall number of partitions can exceed four when you include logical partitions inside the extended area. This is why newer schemes like GPT are used when more than four partitions are needed.
