In que 12th.....as per your concept there will be two answers NH3 and BF3..... But both the structures have covlent bonds... SO3 is the only structure which has two dative or coordinate bonds BF3 forms dative bond when it gains pair of electrons. Example H3N••BF3 Or H3N:-->BF3 In this N is providing both the electrons to the B which fulfill the octet rule.
The molecule SO3 has two coordinate bonds but that structure is not the most stable form as it carries a formal charge. Hence, it doesn't show dative bonding.
One of the most well-known examples of dative bonding is the bond between ammonia (NH3) and boron trifluoride (BF3). The boron of BF3 has only six valence electrons and requires two more electrons to satisfy the octet rule.

Good evening ma'am
Q.12 dative bond present in SO3 ..?
Bf3 have a covalent bonding .. plz clarify my doubt
