1.
According to IUPAC nomenclature, we have to first select the longest rootword, which we see here is clearly pent. Now we have to name the carbons such that the (alkyne) gets the lowest possible number. so the -yne will be given the no 2, after this we will select the prefix (ex : for chlorine we use chloro). At last we finally name the compound
5-chloro-4-methyl-2-pentyne
Hence option (b) is correct.
