The observed group segregation index measures the extent to which different groups (in this case, Muslims and Christians) tend to marry within their own group. It ranges between 0 and 1, with higher values indicating greater segregation. 
To calculate this index, we use the formula: 
OSG = (endogamous marriages within group 1 + endogamous marriages within group 2) / (total marriages)
For Muslims: OSG = 150/200 + 50/100 = 0.875
For Christians: OSG = 50/100 + 50/100 = 1.0
Total: OSG = (150+50)/(200+100) = 0.67
Therefore, the answer is B (0.67).
