To round the decimal number d = 123.1245 to the nearest hundredth, we consider the digit in the thousandth place, which is 4.
Since 4 is less than 5, we round down, meaning the hundredth place remains unchanged. Thus, d* = 123.12.
To find the value of d* + d, we add the rounded value d* to the original value d:
d* + d = 123.12 + 123.1245 = 246.2445.
Therefore, the value of d* + d is 246.2445.
Hence, the correct option is B.

To consider to the nearest hundredth, we only consider the digit in the thousandths place and ignore all other digits.
The thousandths digit=4
So, we round down
d*=123.12
So, d+d*=123.1245+123.12=246.2445
