The correct answer is - a heterozygous individual with widow's peak.
Explanation:
In the given case, the dominant character is the widow's peak that is represented by the allele W and the straight hairline is a recessive character represented by the allele w. So, if an individual has both dominant alleles WW it means this individual has widows peek as W is the dominant allele and if this individual has ww allele it means the straight is expressed as no dominant allele to mask the effect of recessive allele w.
In the case of heterozygous that means one copy of dominant and one copy of recessive allele is present that is Ww then this individual have a widow's peak due to the fact that dominant allele will mask the effect of recessive allele.
