Hi, Shagufta Parveen
PubMed is just a subset of Scopus.

Article Comparison of PubMed, Scopus, Web of Science, and Google Sch...
Dear Shagufta Parveen ,
PubMed is a reliable resource for biomedical literature (quite often Life Science in general), see also:
Williamson, P. O., & Minter, C. I. (2019). Exploring PubMed as a reliable resource for scholarly communications services. Journal of the Medical Library Association: JMLA, 107(1), 16.
Scopus is considered as a reasonably good indexing service, but unfortunately it is (looking at multiple cases here on RG} not free of predatory journals and is rather slow in detecting hijacked journals.
So, PubMed is better, but it covers a smaller number of disciplines.
Best regards.
PS. Johnson Masinde PubMed covers indeed in terms of different disciplines a subset of those in Scopus. But in terms of indexing PubMed journals are often both indexed in Scopus as well as in Clarivate indexes (SCIE and ESCI).
Dear Shagufta Parveen
The comparison could be between Scopus and Web of Science (ISI). Web of science is much more trustable and reliable than Scopus.
if you compare both of this. for example ISI had 28 rules to be completed or examined before published while scopus only 14 rules to accomplished to be done. twice much a much payable hehe.
