Answer: Option A
Solution
Answer: Option A
Solution:
If the radix parameter is omitted, JavaScript assumes the following:1. If the string begins with “0x”, the radix is 16 (hexadecimal)
2. If the string begins with “0”, the radix is 8 (octal). This feature is deprecated
3. If the string begins with any other value, the radix is 10 (decimal)
