Couples Who Are Dissimilar from One Another May Have a Lower

Couples who are dissimilar from one another may have a lower probability of staying married;black couples show greater spousal dissimilarity than nonblack couples.One reason for this may be that:

A) the relatively small size of the marriage pool for blacks limits choices for potential mates,increasing the chance of incompatibility
B) the pattern of behaviors among black men across society makes them less adaptable,causing incompatibilities with most spouses,regardless of race
C) the adage "opposites attract" creates a sense of adventure for some couples that disappears over time,and black couples are more likely to marry earlier,before that sense of adventure ends
D) blacks have similar understandings of gender role expectations within the relationship but diverging understandings of how couples express love
