Assalam u alaikum. It's ok, don't worry. The more R/alkyl groups attached means more stable, or less reactive q k wo electron donating groups hote hain. Tertiary compounds k paas 3 alkyl groups attach hoti hain, lihaza wo reactive nhi hote... nucleophile attack nhi krskta us pr easily. Primary k paas aik hi CH3 attached hai, isi liye wo bht reactive hota hai, uska C+ nucleophilic attack pr expose hota hai. Tho option A sahi hai, q k wo Formaldehyde hai, sirf aik CH3 hai bs. Thori or practice krein, insha' Allah you will ace these kind of questions.
